Adama: Mr. Hoshi, order nuclear ground-strike missiles into launch tubes 4 through 10.
Hoshi: (On the intercom) Aye, sir. This is a nuclear mission order...
Beating the crap out of a Cylon with a flashlight from back in the miniseries.
There's the moment in "Resurrection Ship Part I" where Roslin is attempting to cool tensions between Adama and Admiral Cain and points out that the Pegasus would have the advantage in a fight. Adama's response? A disdainful snort and a muttered "wouldn't count on it.".
The movie BSG: Razor the flashbacks show a young Adama beating the crap out of a Cylon in free fall. Awesome
"Exodus, Part 2", when the Galactica makes a rescue run of all of the humans on New Caprica. Various awesomery occurs on the ground, and then a small dot in the sky is revealed to be the Galactica in freefall, which scrambles all of its Vipers and then jumps back into space just before impact, aka The Adama Maneuver.
With prompting from Starbuck, Lee makes possibly the biggest diplomatic breakthrough of the series with the Cylons by offering the way to Earth for both of them...
D'Anna All this has happened before.
Lee: But it doesn't have to happen again.
What about Lee Adama's grenade? When Lee and Kara are trying to get past the guards guarding the Cylon prisoners, Lee casually throws a grenade down the hallway. The guards scatter, then he and Kara shoot them down. As Kara ducks behind cover, Lee walks over to the grenade and picks it up. "I never pulled the pin."
Made all the more awesome when Starbuck scowls at him, to which he replies "You would have loved it if it was your idea."
Also, it may have been inspired by a deleted scene in Serenity.
Shortly after realizing that he's a Cylon, Galactica comes under Cylon attack, and Saul makes his stand:
Saul: My name is Saul Tigh. I'm an officer in the Colonial Fleet. Whatever else I am, whatever else it means, that's the man I want to be. And if I die today, that's the man I'll be.
In the midseason break for Season 4, D'Anna is back and being just as much of a bitch as ever. In order to stop the Cylons killing the hostages, Colonel Tigh confesses to Bill that he's a Cylon—and offers himself as a counter-hostage, knowing that even if the Final Five could resurrect normally, the Resurrection Hub is gone and D'Anna wouldn't dare doing it if there was a risk.
Saul: (as Lee hesitates to eject him from an airlock) What are you waiting for, Apollo? Do it.
Tigh has an early one when trying to motivate Starbuck to get back to work after her knee injury.
Tigh: The chief wanted me to kick your ass out of bed so you could help figure out that Raider of yours but, clearly, you still need the rest. So take your time, no rush.
Starbuck: Do you actually think that reverse psychology crap is gonna work on me?
Tigh: I really don't care what you think, Lieutenant. All I know is that every day you spend in that bed is another day that I have my opinion of you confirmed. As you were.
The episode "The Woman King" might not be a fan favorite, but it does contain a CMoA for Tigh. Four words: "SHUT THE FRAK UP!"
Standing up to Hammerhead, fully admitting his responsibility for the Gideon massacre while pushing his forehead against Hammerhead's gun barrel. Then, when Hammerhead hesitates, he reaches up and pulls the gun away, and delivers this devastating one-liner:
"Gideon was an accident. This (nods to the pistol) is a choice."
In season one, Starbuck crashes on an barren wasteland planet and, with a busted knee and only a few hours of oxygen with her, fixes and pilots a Cylon raider she had just shot down, and manages to convince everyone to not shoot her with with her name taped on the wings.
Lee Adama has just flown from Colonial One to the Galactica to confirm his father's "release" of Tom Zarek. Upon landing, he is captured by mutinous crewmen and marines intent on killing him. One of them (Connor) asks him "Where are your precious Cylons now?" The next sound he hears is Kara Thrace shooting his would-be executioner. She doesn't hesitate to wound another mutineer who objects, saying "I can do this all day."
"Follow me. Please."
In the miniseries, pushing Lee's Viper back into the hanger after it's disabled.
In Razor, she lands a Viper on zero fuel, after turning around in Pegasus' landing tube to blast the Cylon ship chasing her.
The writers apparently had a Throw It In moment for Kara in the final episode:
Apollo (meeting Kara's squad inside the Cylon colony after a delay): "Where were you?"
Starbuck: "Stopped for coffee."
Cally is being held hostage after a prison riot. One of the prisoners tries to rape her, and she bites his ear off. Later on while recovering in sickbay, she confesses that "He's lucky that's all I bit off."
Particularly notable as the original script had Cally dying after the prisoner shot her for biting off his ear, but everyone quickly realized that it made the character far too interesting to not make more use of.
Gina, killing Cain.
Cain: Frak you.
Gina: You're not my type.
This is even more awesome if you've seen Razor and know that Cain and Gina had been lovers.
Clubbing D'Anna over the head with a rock.
D'Anna: "God loves me."
Caprica Six: "He'll see you again soon."
Snapping Boomer's neck after Boomer had threatened to snap Hera's, then escorting Athena and Hera back to Galactica, knowing full well the reception she would get.
Helo, one of the series' quieter characters, has had a few in this troper's eyes, but the one that comes to mind most readily is when he's confronted by President Roslin after "killing" his Cylon wife so that she could rescue their infant daughter Hera from the Cylon fleet. He looks her straight in the eyes and, with restrained but overt rage in his voice, says that he wouldn't have had to do it if she hadn't deceived him about Hera not dying shortly after her birth. The normally stoic Roslin is actually shaken by this.
Punching Saul in the face, after getting fed up with the insults towards Sharon. Frankly, he just did what more than a few viewers have wanted to do for a while.
Killing Sharon's attempted rapist aboard the Pegasus. He may be a really nice guy but You do not hurt Sharon Valerii and live to tell about it when Karl Agathon is around.
Except that: 1) Oh, yeah, you do. Big time! 2) That wasn't Sharon Valerii.
In "Home, Part 1", the group searching for the tomb on Kobol is under attack by a trio of centurions. Athena runs through the hail of gunfire, retrieves a grenade launcher from a dead soldier, overpowers Apollo (who thinks she's going to turn on them) and nails the last centurion with a grenade from at least twenty meters away. Worth noting that she did all of this while her forearms were cuffed together, so she made that shot one-handed.
Apollo: You gotta be frakking kidding me.
Starbuck: Not bad.
Best of all, in the next episode? Athena is being allowed to walk around with no restraints anymore.
Redirecting a Cylon virus back at the gigantic fleet of Raiders about to attack, proving her trustworthiness to much of the crew.
Roslin has a crowning moment of awesome too when everyone is evacuating New Caprica...
Laura Roslin: Tom, you go that way. Head to the shipyard.
Tom Zarek: You're coming, right?
Laura Roslin: [points to Colonial One] My ship's up there.
Laura Roslin gets one with her resolute promise to Zarek after he tries to demoralize her into surrendering with a lie. Namely, that Tigh and Adama had been executed.
Roslin: No. Not now, not ever. Do you hear me? I will use every cannon, every bomb, every bullet, every weapon I have down to my own eye teeth to end you! I swear it! I'M COMING FOR ALL OF YOU!
YMMV on this one, but Roslin slapping Tigh on New Caprica when he asks if she's siding with the Cylons is pretty damn satisfying. Colonel Badass he may be, but Tigh really needs a slap once in a while.
Roslin telling Adama quite calmly that he has to kill Admiral Cain in the 'Pegasus' arc. When the chips are down, she's the only one determined enough to state out loud what has to be done; the other characters are shocked and hesitant at the suggestion.
Make that her entire reaction to the Galactica/Pegasus standoff, where she sits them down on Colonial One and proceeds to smack them both down like naughty children who have been misusing their Battlestar privileges.
Doubles as Fridge Brilliance, when you remember that Roslin was Secretary of Education before the Fall of the Colonies, and a school teacher before that. She's doing exactly what a teacher would do with two unruly students: calling them into her office and giving them a talking-to.
Virtually the entirety of the miniseries, some of which we only find out in "Epiphanies". As Jacob from TWOP put it so succinctly:
"First she got inoperable cancer, then she solved a union crisis verging on bloodshed, then she watched some people making out hardcore in public, then she got dumped and fired, then took a trip to a museum, then the whole world ended, then she got LBJ'ed, then she killed a few thousand people, then she freaked out for a while, and then she may or may not have grabbed a nap. And she did all this with total class, while looking — at worst — a little tired, with everybody treating her like she was completely slow the entire time. Jack Bauer's like, "Lady, I gotta hand it to you." "
Starbuck spends nearly the entirety of "Flesh and Bone" trying to interrogate a copy of Leoben as to the whereabouts of a bomb planted somewhere in the fleet, and not only does she obtain no information whatsoever she lets Leoben the get under her skin big-time. At the end Roslin gets him to cough up the location of the bomb (or rather the fact that there was never a bomb to begin with) in less than two minutes by simply threatening to have him thrown out of the airlock. Which, for good measure, she then does anyway with these immortal words:
''"Throw it out the airlock."
Baltar evangelizing a Centurion (note that this is after the Centurions gain sentience).
His noblest action was in the season 4 mid season finale, talking D'Anna down from nuking the civilian fleet, convincing her to at least try and work with the humans. It saved the fleet and was something no other person could have achieved thanks to his personal history with D'Anna and his extraordinary charisma, as well as highlighting his path towards redemption (though whether his crimes can ever really be balanced out is another matter).
After being nearly killed by Gaeta, he testifies against him in the trial.
Gaius Baltar: "We all know that this man tried to stab me. And you missed! BUTTERFINGERS!"
Killing Crashdown after he goes off the deep end, then covering Tyrol as he blows up the dish that would let the Cylons shoot down the ships about to rescue them.
The love for Doc Cottle as a character occurred in "Pegasus" after the Attempted Rape of Sharon/Athena at the hands of the Pegasus officers. Sharon is recovering in sickbay, and Adama isn't quite sure how to handle it. Cottle, however, has no such problem:
Adama: What happened to you tonight...
Cottle (quietly furious):...was unforgivable.
Cottle gets a subtle but long running one throughout the entire series: he has no reservations about treating anyone, be they military, civilian, Human or Cylon. Even though he is a member of the Colonial Military, he is first and foremost a doctor and a healer, making him one of the few main characters, more or less, who survive the entire series with no dubious morality moments.
Tyrol gets in on the awesome action. Zarek and Gaeta are about to jump away, which would mean even if Adama does succeed in getting his ship back he'll be surrounded by ships disloyal to him and isolated from Roslin and the basestar Chief singlehandedly sabotages the FTL drive, and what makes this all the more awesome is that he hadn't had any communication with Adama. He simply figured out what he needed to do on his own.
At the end of the episode "Lay Down Your Burdens Part II" the occupying Cylons march past the colonials. After a year of civilian life, Chief simply turns to Starbuck and says "What'd we do now, Captain?" Absolutely perfect Chief moment.
Sure, it's a bit of a What the Hell, Hero? given what follows, but when the Final Five link up and share memories to give the Cylons resurrection technology, Tyrol learns that Tory killed Cally, his wife. He breaks out and strangles her, complete with a look of completely unrestrainedRAGEon his face.
Romo Lampkin stabbing a Marine in the neck with a pen and killing him and then referring to him as his "pen pal".
In the miniseries, the Colonial fleet is ambushed by the Cylons. Galactica is an undermanned, antiquated ship two days from being turned into a museum. Adama is outnumbered, outgunned, he has no ammunition, no backup, no information, and one of his flight decks has been turned into a frakking gift shop. What's his response? Stand and fight! Get me some bullets!
Lt. Felix Gaeta
In "The Oath", Felix lets William Adama absolutely have it when it counts most, standing as a voice for all the survivors of New Caprica:
"You swore the same allegiance! What happened to your oath? For seven years I have done my frakking job and for what? To take orders from a Cylon? To let machines network our ship? No, you...you are not the leader you were when we started. You're just a sad old man who has let his heart and his affection for a Cylon cloud his judgment!"
And heaps coals of fire on Starbuck's head in "Collaborators" with one quiet line: "I did what I could. I don't know what more I could have done."
The Great Cylon Turkey Shoot. That is all.
The last scene of Pegasus is a CMOA for both Cain and Adama.
Helo and the Chief overcoming their mutual animosity and throwing away their careers, and possibly lives, to rescue the pregnant Athena from a rape in progress. Intense, heavy and somehow totally awesome all the same time.
During the mutiny, Commander Adama and Colonel Tigh beat the crap out of their armed guard. Standard action fare until you remember that these are supposed to be two pudgy old guys.
Supposed to but actually not, if you do not discount the scenes of old guy Adama beating the shit out of young Adama in the boxing ring.
Also Tigh was in full Cylon mode by this point too, and the Final Five were at the least considerably stronger than your average human.
Adama and Tigh running around the ship, dual-wielding guns (an assault rifle and pistol), shooting down anyone who gets in their way as they take back Galactica.
Apollo, having just ejected from the destroyed Blackbird stealthfighter, discovers a rip in his suit. After seeing this, the camera pans back to reveal Galactica and Pegasus beating the absolute crap out of two Basestars, whilst the Vipers blow the Resurrection Ship to hell. Totally. Freaking. Awesome.
Under the command of Apollo, the Pegasus jumps into New Caprica, guns-a-blazin', destroys two Basestars and damages a third, before going nuclear WITH ALL HANDS STILL ALIVE.
To elaborate, Lee Adama sets it on a collision course with all the automated systems running as he and the crew make a run for it. As they escape, we're treated to a shot of the Pegasus plowing through space, everything on it firing at the Cylons attempting to stop it. Then it rams into a Basestar, explodes, then a flying landing pod takes out a second Basestar.
The entirety of the rescue mission on New Caprica could be listed here.
In the Grand Finale, as Baltar and Caprica Six bring Hera to CIC, amid the human-centurion fighting going on, we see Adama kicking a centurion to the ground and shooting him.
A meta example. The fact that they were able to take a series that EVERYONE, fans and haters of the original series, thought was going to suck and turned it into one of the most critically acclaimed series in television history is quite an accomplishment.
The Galactica itself. It went through everything in the series, despite the fact that corners were cut during its construction. That's right. Everything it did was done while it was hobbled by poor construction. In a meta example makes sense, because if it was built to specs, it would gone a whole lot farther.
