* In "Dear Sis", when Fr. Mulcahy feels that he's useless to the unit. At the end, Hawkeye and the rest of the 4077 let him know just how important he is to them, and sing "Dona Nobis Pacem." Also in the same episode, the look on Major Winchester's face when he opens his Christmas present to see the tobogganing cap he wore as a child--a little piece of home thoughtfully sent for by Mulcahy. Dona nobis pacem.
** It's even more heartwarming when you realize that it was actually Radar who sent out for the hat and made it seem like it was Mulcahy's doing, thus helping both the chaplain and the surgeon truly connect to the holiday season.
*** Radar may have sent for the cap, but it was still Father Mulcahy's idea for him to do so.
* Several reactions from Season 9 episode "Letters", most especially the one Charles gets from a girl named Virginia. She writes him a letter about how beautiful Maine looks in fall, sending along a fallen leaf from a birch tree. Charles, who has so far written two letters: one angry and one sarcastic, gets a look on his face of absolute joy and writes a truly thankful letter.
-->'''Charles:''' ''(dreamily)'' Autumn in New England...
* "Potter's Retirement" has the colonel planning to hang it up after receiving the news that negative reports about his leadership are coming from inside the 4077th. The party in question turns out to be a corpsman acting as [[TheMole mole]] for a general who holds a grudge against the camp. After things have been sorted out we get a scene in Potter's office where Hawkeye, BJ, and Radar let him know how much his leadership is valued and beg him to stay, Hawkeye even [[FirstNameBasis addressing him as "Sherman"]].
** The absolute disgust Potter has in his voice when he confronts the mole shows just how protective he is of his men. He's in full PapaWolf mode there.
* As part of a conscious effort by the writers to distance the character of Charles Winchester from that of Frank Burns, Winchester was a part of numerous heartwarming moments over the course of the series, if usually in the episodes' B plots.
** Early in the aforementioned "Dear Sis", Mulcahy had tried to solicit a donation from Winchester to buy some toys for the orphanage, and had been firmly rebuffed (Winchester claiming that it was a "useless gesture" to raise children's hopes only to have them dashed again after Christmas). After Radar gives him the toboggan cap and tells him it was Mulcahy's idea, Winchester tearfully accosts the padre and hands him a wad of bills, telling him to "buy (the orphans) whatever they need." Starting to leave, he turns and hands him ''another'' wad of bills, telling him in an emotion-choked voice to "buy them whatever they ''don't'' need."
--->'''Mulcahy:''' Major, are you all right?
--->'''Winchester:''' [putting his hands on Mulcahy's shoulders] You ''saved'' me, Father. You lowered a bucket into the well of my despair, and you raised me up to the light of day. I thank you for that.
** The B plot in "Run for the Money". A wounded Private is teased by the other men in his unit and his Sergeant for his stutter, and has been called a dummy for so long that he believes it. Major Winchester rips into the men who make fun of him and tells the Private that he's seen his IQ score and that he's very intelligent, but needs to believe in himself. He then recites a list of famous people who stuttered and sends the Private off with a copy of ''Literature/MobyDick'', saying that it's fit for a man of his intelligence. He then retires to his tent and listens to a recorded letter from his sister back home...who stutters.
** The B plot in "Death Takes a Holiday". Winchester earns the contempt of the rest of the camp by not donating to the Christmas charity drive... because, unbeknownst to them, he is instead following a family tradition of donating a large consignment of confectionery from an upmarket Boston supplier to a local orphanage. He is surprised in the act by the orphanage director, who invites him in to meet the orphans; Winchester declines, saying that the gift must be given [[AnonymousBenefactor anonymously]]. He later discovers at the camp Christmas party, to which the orphans are also invited, that the director immediately sold the chocolates on the black market. Charles confronts the director, believing that he pocketed the money, only to learn that the money was used to purchase enough rice and cabbage to feed the orphans for a month. He is immediately humbled by the revelation, and returns to the Swamp. Klinger overhears the conversation and follows Winchester to give him a plate of leftover food from the Christmas party... on condition that the gift must be given anonymously. They exchange a "Merry Christmas", addressing each other not as "Klinger" and "Major" but as [[FirstNameBasis "Max" and "Charles"]].
*** Charles' initial confrontation with the orphanage director also counts. Charles, who's usually pretty aloof, looks about two seconds from ripping the man's arm off and beating him with it-- and ''sounds'' about three seconds into the act.
** The B plot of "Sons and Bowlers". Hawkeye's father goes in for surgery Stateside, but his survival is not guaranteed. Winchester overhears Hawkeye trying to get through to the hospital where his father is being treated on the camp phone, and proceeds to spend the night keeping vigil with him until they can get word that the elder Dr. Pierce has made it through. As they discuss their relationships with their fathers (a discussion in which we learn that although Charles Winchester II wanted only the best for his son, he was nevertheless a typical emotionally-distant patriarch), Winchester calls Pierce fortunate in that while Charles has a ''father'', Hawkeye has a ''dad''.
--->'''Hawkeye:''' Charles, you've never told me anything like this before.
--->'''Charles:''' Actually... [[FirstNameBasis Hawkeye]]... I've never told you ''anything'' before.[[note]] The only time in the series when Charles non-snarkily addresses Hawkeye by his nickname.[[/note]]
** The B plot of "Morale Victory". Charles operates on a soldier who had been a pianist until he was wounded in the right hand. Charles, badly shaken by the soldier's despair at his aborted career, remembers that the composer Maurice Ravel created [[https://www.youtube.com/watch?v=KJTUUKAdZDU music which could be played with only one hand]], and urges the former pianist not to give up on music, since the real gift was "in your head, and in your heart, and in your soul"; that he still had "the baton, the classroom, the pen. I have ''hands'', David, hands that can make a scalpel sing. All my life I have wanted to play. I can play the ''notes'', but I cannot make the ''music''." The scene ends with the music being played, one handed.
* There's plenty from the finale:
** Klinger loving Soon-Li enough to stay in Korea (go back to the early episodes and you'll realize what a surprise that must have been) to help her find her family. Doubles as a FunnyMoment:
---> '''Klinger''': I can't believe I'm saying this...I'm staying in Korea!
** Hawkeye and BJ giving Potter a respectful, silent salute. Twice as heartwarming because you can literally count the number of serious salutes that Hawkeye has given ''anyone'' throughout the series on one hand.
** Potter giving Margaret a kiss on the forehead and hoping that her personal life will be just as good as her professional life.
** Potter saying goodbye to Sophie. (Doubles as a TearJerker.)
** Hawkeye telling BJ "I'll never be able to shake you" and the deep, desperate hug between the two of them right afterwards.
** Charles saying goodbye to Margaret. Previously, he had taken back a book of poetry he had given her, much to her disappointment. When it comes time to leave camp, he returns the book to her, now with a written message inside the cover, and kisses her hand, a true OfficerAndAGentleman.
** Winchester's departure from the 4077, remaining as dignified as ever, even though he is riding in a ''garbage truck''. He comments that it's quite appropriate, considering he's leaving a dump. His final line:
*** It's a bit of a CallBack to Hawkeye's Last Will and Testament, when he commented that Charles never lost his dignity, even in the most undignified situations.
** The "goodbye" stones are a two-fold CrowningMomentOfHeartwarming: not only from BJ to Hawkeye (giving him the goodbye that he wanted from BJ and - it's implied - from Trapper), but also from the show to us.
** The supporting cast has always gotten more love than most shows will give, to the point that the extras remained almost static in the later years of the show. The supporting cast was given special attention, including one episode showing Kellye being the backbone of the nurses and another where Goldman getting sick was a major plotpoint. Thus, it was especially touching in the finale when various supporting characters got to stand up and announce where they were going after the war. Gave a real sense of family and realism to the moment, as many shows would have focused exclusively on the main cast.
* Speaking of Trapper, there's his exchange with Hawkeye when they think he's going home, in "Check-Up":
-->'''Hawkeye:''' Thanks, Trap.\\
'''Hawkeye:''' You made it bearable. I was lucky. You were honest, and open, and let me lean on you.\\
'''Trapper:''' [holding back tears] No charge.
* Henry's goodbyes to everyone in "Abyssinia, Henry"... before that last O.R. scene shifts everything into full-on TearJerker territory.
** Speaking of Henry, in Season 1's "Showtime" he's depressed due to not being able to see his newborn son. Near the end of the episode, [[spoiler: Radar brings in a Korean woman and her infant son, so Henry could hold the baby for a while. Edges into being a TearJerker, as well.]]
** Also from "Abyssinia Henry": As Henry is heading to the chopper, having said his goodbyes, he notices Radar stading there, giving him a salute. He hesitates, then runs over to Radar, tells him he'd better be good, returns the salute, and then hugs him. Considering the fact that he had been trying to avoid getting mushy with Radar (Radar had essentially told Henry that he considered Henry his father, given the fact that his real father had died when Radar was an infant), it shows just how much Radar really meant to Henry.
* In the "Bug Out" episode, the 4077th is forced to relocate in response to rumors of the encroaching Chinese advance. As part of that, they find an abandoned schoolhouse that they believe is perfect for setting up their army hospital... except that it's already occupied by several Chinese women who are using it as a brothel. After some heated back and forth between the Madam and Colonel Potter, the ladies take an intense interest in Klinger... 's rack of fall gowns. Klinger, for the good of the unit, forfeits the entire rack of gowns, and 'buys' the schoolhouse for them. As Potter commented, "Corporal Klinger, that's the finest act of bravery I've ever witnessed."
** It's played off for laughter, but the real heartwarming part is that while Klinger expresses skepticism at "doing it for his country," he warms up considerably and finally agrees when Col. Potter asks him to do it for Toledo. Klinger really loves his hometown.
* Anytime the 4077th get a home movie from their families is both this and a TearJerker.
--> '''Hawkeye:''' Henry, if you don't give the order to cry, I will.
** The one BJ gets from Peg in "Oh, How We Danced" is particularly heartwarming. First, that Hawkeye would go to the trouble of setting BJ up so he could record how the day might go. Then getting it to Peg in time for her to make the movie and send it back. Then the surprise party. The look of absolute joy and pride on his face when he sees Erin in the movie will have you ready to cry as well.
* The end of the "Rainbow Bridge" episode, where Radar comes to help Hawkeye and Trapper pack for their well-deserved (and much-delayed) R&R in Tokyo. As he works, he turns his back on them and expresses how impressed he is with the work they do, offhandedly adding, "If you ask me, you guys are like supermen." Turning around, he finds them collapsed in exhaustion into their cots... so he quietly covers them up with blankets, whispers, "Goodnight, supermen," and leaves them to sleep.
* In "Fallen Idol", Hawkeye hands Radar his Purple Heart medal, and then gives him one of the very few genuine salutes the good Captain ever did.
* When Radar is sent home, he leaves behind his beloved teddy bear, indicating both that he is now a man and that he will always be with the unit in spirit.
** Which leads to another heartwarming moment in the penultimate episode, when Hawkeye donates the bear to the 4077th time capsule to stand for all those who came to war as boys as went home as men.
* Any scene during Margaret's transition from antagonist to sympathetic character where she tries to make friends. There are moments where she seems less like a formidable, confident major and head nurse and more like the unpopular kid from middle school. One example is when she awkwardly asks the doctors if she can have coffee with them, then gets really excited when they say yes. The end of "The Nurses" also qualifies.
* "Movie Tonight" is an episode full of heartwarming. To start with the entire camp are at each others throats, getting angry over everything. When a movei Potter ordered arrives, he gets the entire camp (minus the nurses, who are going to dinner at I-Corps) to meet in the mess tent for the screening. The projector keeps breaking during the movie, and the camp start getting angry again. To stay calm they all sing "Gee, Mom, I Want to Go Home", during which the nurses decided to stay at the camp instead of going to dinner, watch Radar do impressions of famous people, and play the game no one has been waiting for: the Father Mulcahy sound alike contest! When the movie starts playing again, there's a shoot out scene, during which the camp play along and pretend they've been shot and are lying on the ground. An ambulance driver pulls into the camp with wounded and finds them pretending to be dead, and during surgery everyone is singing a song from the movie.
** With a bit of MoodWhiplash as Frank tries his own verse of the song, which falls completely flat as he does it several minutes late and it's basically an angry threat to Hawkeye and BJ.
** And RealLifeWritesThePlot as well. The Mulcahy sound alike contest was based on one the cast did frequently behind the scenes.
* "Preventive Medicine" is one of the darker episodes of the show, with BJ and Hawkeye having a screaming fight over whether or not to perform a medically unnecessary operation to get a reckless colonel off the line. Hawkeye does it, compromising his morals as a surgeon, and then it turns out to be all for nothing. Then, at the end, as Hawkeye is sitting alone on his cot in despair, his face in his hands, BJ walks over and places a hand on his friend's shoulder. For a few silent seconds, they grip each other hard before getting up and walking away together. The HeterosexualLifePartners may scream, may crack, may vehemently disagree with each other, but they still love and stand by one another when needed. And it goes deeper still, as the views Hawkeye and BJ held were the ones that Alan Alda and Mike Farrell held. That moment they take before they head out to surgery was a bit of a reconciliation between the actors, not just their characters.
* Anytime Margaret and Hawkeye have a FriendshipMoment. For example, when she tells him she thinks she might be pregnant he is genuinely overjoyed for her [[spoiler: and later a bit sorry for her when it turns out she's not]], Hawkeye is the one who comforts her when she breaks down in "Images," and Margaret's divorce is the final straw that inspires Hawkeye to take on the peace talks in "Give Em Hell, Hawkeye." It's really heartwarming to watch them move from deep dislike mingled with grudging respect in the early episodes to a genuinely warm friendship by the end of the show.
* There is the classic episode, "Point of View" where we see all the action through the eyes of a soldier and Col. Potter confesses that he feels terrible that he forgot to telephone his wife, Mildred, on their anniversary because he was so busy with a rush of wounded. The soldier tells Hawkeye, and the doctor and Radar contact Mildred to explain the situation and she agrees to wait on the line for Sherman, with the instruction that he is to be told that she understands the weight of his duties.
** In the same episode, Private Rich wakes up from surgery and Hawkeye blocks off his tracheotomy tube to see if he has regained the ability to speak. After he's said a few words, the doctors are about to leave and let him rest, but he gestures for Hawkeye to block off the tube again so he can say, "Thank you."
* The B Plot of the episode "Dear Mildred" focuses on Radar's attempts to help an injured horse - and hide the horse from Potter. In the end he decides to give the horse to Potter as an anniversary gift. Not only does this ensure that the horse will stay in camp and Radar will get to take care of it, but it also helps Radar to become more at ease around his new commanding officer.
-->''(Potter slips on freshly made horse manure in his office)''
-->'''Burns:''' That's disgusting!
-->'''Potter:''' [grinning] Son, to me that's a tiptoe through the tulips!
* The 4077th coming together to put on a wedding for a South Korean ping-pong champion, including Col. Potter giving the bride away and Margaret helping to sew (or at least alter) the bride's wedding outfit.
** Father Mulcahy also explains the ceremony to the other members of the 4077th, showing just how much he respects the Korean people and their traditions.
* In "Where There's a Will, There's a War", Hawkeye writes out his last will and testament in the event that he is killed while serving in an aid station under heavy fire. While writing it, he reminisces about his friends and writes out something about each one of them that he loves. The one person he can't seem to find the right words for is BJ, until he has an epiphany and [[spoiler: leaves to Erin Hunnicutt a list of all the people her father has operated on during the war.]]
** In a flashback scene from this episode, Hawkeye notices a copy of ''Life'' magazine on Klinger's desk, which happens to contain a photo spread of coastal Maine. Hawkeye is excited to see pictures of his home state, and Klinger dismissively lets Hawkeye keep the mag. After leaving Klinger's office, Hawkeye notices a soldier eating a large salami. The soldier tells Hawkeye that Klinger traded the salami for his ''Life'' magazine.
* It's a bit twisted, but in "Rally Round the Flagg, Boys," a GI is disgruntled that Hawkeye took a wounded North Korean officer ahead of his friend. Throughout the episode, the GI is giving Hawkeye trouble, and a few jokes are made at Hawkeye's expense about how he's short-tempered. The GI finally confronts Hawkeye in his tent, who is reluctant to hurt him for a number of reasons. He's got Hawkeye backed into a corner, when an absolutely furious BJ bursts in and grabs the GI by the shirt. BJ is shaking the man and saying he ''should break his neck'' when Hawkeye grabs him to get him to cool off. Shows just how protective BJ can get of his friends.
* In "Dear Comrade", the episode is told from the perspective of a North Korean spy posing as Winchester's houseboy, trying to find out how the unit had such a high success rate. The group is so unorthodox and loose he finds it impossible for his faction to replicate it. He does, however, fabricate that he has to stay ''a little longer'', because he'd grown so friendly with the gang, even Winchester - after the spy tells him off for his snobbery and mild racism, Charles just laughs and shows he's NotSoAboveItAll.
* In a small gesture towards his nemesis, Hawkeye's reaction to Hot Lips bragging about her engagement around a clearly depressed Frank Burns. Hawkeye has no reason to do it, but even he believes that Frank should be cut some slack. Further punctuated at the end of the episode, where he and BJ join Frank in genuine, honest laughter after he finally gets a jab at Houlihan.
* "Quo Vadis, Captain Chandler".
-->'''Chandler:''' Bless you, Walter.
** This is not only after Radar had asked him to bless his teddy bear, but also the first time we learn Radar's given name courtesy of him telling it to Captain Chandler.
* In one episode, Potter's horse Sophie goes missing. Potter is understandably angry, until he learns that the guy who stole her was an old Korean cavalry officer who just wanted one last ride before dying. Potter gives Sophie to him as a gift, at which the man tears up and bows to Potter in respect. He dies the next morning, but his granddaughter says that it was the happiest he had been for a long time.
* In "O.R.", Hawkeye operates on a wounded Ethiopian soldier. Awhile after the patient wakes up, Klinger brings him to Hawkeye on a stretcher and says the Ethiopian wants to say something to the doctor. He says a few words in his native language while smiling widely and Klinger says he thinks the patient is thanking Hawkeye. As he's about to be taken to Post-Op, he grabs Hawkeye's hand and kisses it. A visibly moved Hawkeye says to Henry, "That's got to be the nicest fee I ever got."
* It's cut from syndication, but a scene between Charles and Colonel Potter is actually rather sweet. Both of them have come down with the mumps, which can result in a loss of fertility in adults. Charles is freaking out over not being able to father a child, and is practically in tears. Potter talks him down.
-->'''Charles''': The thought that Charles Winchester the Third could be Charles Winchester ''the last'' ...
-->'''Potter''': Look, you've got a mild case, you're getting plenty of sack time, you've gotten a rump-full of gammaglobulin, chances are you'll grow old in a house full of little roman numerals.
* Blake's last words to Radar before he leaves. "You behave yourself or I'm gonna come back here and kick your butt". [[spoiler: Doubles as a TearJerker when you find out Henry won't be coming back.]]
* In "U.N., the Night, and the Music," a rather good-looking Swedish doctor arrives, and Margaret almost immediately falls for him. Unfortunately, he's had an injury in the past (nerve damage after his jeep hit a mine) that prevents him from having any sort of sexual relationship with Margaret. Hawkeye agrees to [[MomentKiller run interference for the man]], increasingly frustrating Margaret. Eventually, the doctor comes clean with her and tries to leave gracefully. She immediately stops him and asks if he wouldn't just like to stay and talk for a while. He practically falls over himself agreeing, implying this is the first time anyone's accepted his condition. Then, the next day, Margaret confronts Hawkeye.
-->'''Margaret''': [angrily] And ''you''! [smiles] Thanks for trying to be a jerk.
* One of the storylines in "Showtime" involves Father Mulcahy worrying about how useful he's currently being. Hawkeye assures him by saying, "Some people say that God heals the wounded while the doctors collect the fee. I've done many surgeries beyond my skill to do."
** The same episode has Trapper trying to save a wounded soldier who only gets worse even after the surgery is successful. The two storylines combine when Father Mulcahy is called in to deliver last rites. He takes the man's hand, makes the sign of the cross, and begins to pray when the soldier opens his eyes. Hawkeye asks, "What was that you were saying about not being useful?" while Mulcahy is in disbelief and Trapper wordlessly realizes they've just witnessed a miracle, especially with how close they'd come to losing his patient.
* In "Nurse Doctor," an outcast nurse who was going to resign her commission and go to medical school has decided to give it up after an unfortunate HotForPreacher incident with Mulcahy. Her being Margaret's responsibility, it's Margaret who tells her that she's not going to get to get transferred, nor will she be allowed to quit on herself. The next two weeks (before she gets discharged) will not be fun for her.
-->'''Nurse Harris''': You'll be more than satisfied with my nursing.
-->'''Margaret''': Your nursing duties will only be part of it. For the next two weeks, your free time will be spent with Captain Pierce and myself in intensive study for your medical aptitude tests.
-->'''Nurse Harris''': [[FlatWhat What.]]
-->'''Margaret''': I know how hard it is for a woman to become a doctor, and the Army is no help. But with your skills, you've got a real chance! [smiles faintly] And as long as you're under my command, I'm not going to let you back out.
* Margeret is furious when she realizes her engagement ring is a ReplacementGoldfish, after she'd lost her ring and the guys "found" it for her. (It says, "Over hill, over dale, our love will '''ever''' (not "never") fail".) She's ready to explode when Max gently tells her that she's being unfair, and they only tried to make her feel better. She later lets Hawkeye know it's a replacement, then tells him she likes the replacement better.
