“Obviously, the military has never fought giant robots, and hopefully we never will. But the way this film is structured, if we ever had to do it, this is probably how we would do it,” said Army Lt. Col Paul Sinor, a public affairs officer with that service’s Office of the Chief of Public Affairs.

During one battle scene, members of a joint special operations force are attacked by a Decepticon in the desert of a Middle Eastern country. Using a common cellular phone, the Army commander on the ground dials the Pentagon and tosses the phone to his Air Force combat controller, who directs an Airborne Warning and Control System aircraft to their position. Operators on the AWACS then call in AC-130 Spectres and A-10 Thunderbolt II aircraft for air support.

“Go, Air Force!” an audience member yelled when an AC-130 began firing on enemies with its side-mounted artillery guns. “Yeah, Navy!” belts out a sailor upon seeing a team of destroyers cutting across the shining sea.

Defense Department officials allowed Paramount Pictures to film at Air Force bases in New Mexico and California, and to rent military equipment such as the CV-22 Osprey and F-22 Raptor, which made their big-screen debuts in “Transformers.” F-22s run about $25,000 per hour, according to the rental scale established by the department.
