Continuity mistake: At the end of this scene the shots of Chef and Miss May in the helicopter at the Medevac were done in an entirely different place. All the outside shots of the helicopter have different backgrounds (trees, mountains, tower) from what we saw when Captain Willard first walked around the Bunnies' camp.
Continuity mistake: After the 'Valkyrie' helicopter attack, there's a close shot of a soldier who shouts: 'I'm not going.' Another soldier turns back to the chopper to pull him out. Then there is a long shot of the troops at the choppers and you see the same soldier turning back to the helicopter.
