Visible crew/equipment: When Cowboy, Joker, Rafterman and the other Marines are running across the buildings to get to Animal in the final sniper scene, watch the foreground. Right before they reach Animal, you can see they run by a crouching crew member, in the foreground at the bottom of the screen. (01:38:52)
Visible crew/equipment: When Jim returns to the party with his father after he met the Japanese soldiers, you can see the microphone at the bottom of the screen. (More recent transfers address this and make sure it is not seen).
