* [[spoiler: Hummel's death.]].
* The knowledge that [[spoiler:despite Hummel's impressive military career and the countless sacrifices he made for his country, his actions on Alcatraz ensure that history will remember him as a traitor who endangered the lives of countless innocent people and whose killed an entire Navy [=SEAL=] team. He failed to secure the reparations for his fallen men and also destroyed his own reputation.]]
* His men's LastStand which can be heard over the opening credits:
-->'''Hummel''': "I won't let you down. I won't let you down, son.''
-->'''Marine''': "They're not coming back for us, are they sir?"
* Hummel's speech on his wife's grave:
-->'''Hummel''': I miss you so much. There's something I've gotta do, Barb. Something I couldn't do while you were here. I tried. You know I tried everything, and I still don't have their attention. Let's hope this elevates their thinking. But whatever happens...(he takes Congressional Medal of Honor out of his pocket) please don't think less of me. (he sets the Medal on top of the headstone, leans over and kisses it, and then walks away).
* The [=SEALs=] shooting it out with the Marines [[spoiler:in the showers,]] and [[spoiler:getting wiped out.]]
-->'''Goodspeed''': Don't go!
** Another tearjerker in that scene [[spoiler: is Hummel frantically ordering his men to cease fire, but they can't hear him over the sound of the gunshots or in Frye and Darrow's case likely ignoring him.]]
*** The music (a reprise of the part of the main theme that plays over the LastStand mentioned above) doesn't helps any.
** The FBI personnel watching the entire thing on their monitors, absolutely helpless to stop it. Half of them are ready to lose it completely when they see the aftermath.
** One of the Seals left behind to monitor looks like he's about two seconds away from bursting into tears. Or killing himself.
** Hummel finding a survivor among the [=SEALs=] just in time to watch him die. He then curses his opponents for forcing his hand upon fellow soldiers.
* Hummel threatening to murder a hostage if Mason and Goodspeed refuse to surrender. The man is breaking down helplessly with a gun pointed at his head and the two survivors are forced to listen to the whole thing. Thankfully, Hummel doesn't pull the trigger.
* "How does one weigh human life?"
* Sergeant Crisp's death; he was the only soldier other than Baxter and Hummel to express any misgiving about killing an entire city of civilians, and was a longtime comrade to the general. When pressed by Frye and Darrow to arrest Hummel, he has an attack of conscience before reluctantly approaching the general, only to have a pistol pointed to his throat. He is completely helpless when the shooting starts, and his expression is one bordering on regret.
* Major Baxter's death also counts. He stays loyal to Hummel when their plan falls apart, and when tempted by Frye and Darrow when they mutiny, it seems as though he is about to betray his best friend. Instead, he remains loyal and attacks the traitorous marines, only to die with his friend in an act of SenselessSacrifice.
