Continuity mistake: As stated in another entry, Brown states that they are in a Huey when they are actually shown in a JetRanger. Later on, after twice showing night shots of a JetRanger flying overhead, they are shown in the cargo area of a Huey, then are shown flying and deploying out of a Huey.
Other mistake: At about the 8 minute mark SnakeDoctor is talking on the radio to Bushmaster who is on the ground. There is a few seconds long shot where Bushmaster's earpiece is dangling wires and not connected to his Comms Gear on his vest. That earpiece can't be wireless.
