Early in the film, after the helicopter extracts Hoot from his surveillance mission, they fly over some wild boar. Hoot, who hasn't eaten or slept in two days, takes one look at them.
Hoot: Hey, who's hungry?
He follows this up with the happiest grin you see in the entire movie.
Early on, General Garrison's increasingly-frustrated attempts to get their somali informant to do his job (marking the building where a meeting of high-ranking militia members is going to take place), leading to this exchange:
Harrell: Now he's saying the building is a couple blocks farther down, but if he's seen outside he'll be shot.
Garrison: *thoroughly exasperated* I'll fuckin' shoot him myself! You tell him to park his skinny ass in front of that building. He doesn't get paid until he does exactly that.
Waddell: Now they're shooting at us! [fires off long burst from his M60]
Yurek, after getting separated from the rest of the squad, accidentally comes across Nelson and Twombley, who have also been separated. Twombley mistakes Yurek for a bad guy and shoots at him, forcing him to scramble for cover. He then realizes that it didn't sound like an AK...
Yurek: Rangers? Twombley: Who? Yurek: It's Yurek! You fucking assholes! [Nelson and Twombley quickly communicate with each other] Twombley: Dude, we almost fucking killed you! Well, come to us! Yurek: Fuck you! Come to me!
