What is the biggest military movie/TV goof, basically the military Movie/TV mistakes that annoys you the most?

When a semi-automatic pistol clicks when the trigger is pulled and the slide is locked to the rear! That one drives me NUTS!

It's not just the military. Helicopters. Smoke ALWAYS come billowing out of the OH-58's or Bell 206's BATTERY compartment. Also, when the helicopter cranks and the rotors are at full rpm in 3 seconds. And then the guy who can FLY the helicopter is on the ground shooting at the hovering chopper and doesn't think to shoot the tail rotor, which would knock it out of the sky post-haste.
Also, I've worked on railroads and almost universally they screw up train operation. If a train comes apart while operating, the brakes would AUTOMATICALLY set on both portions of the train. There are so much more, but we'll leave it at that.

NOT aiming, I mean [login to see] rounds fired and not one body, also "thermos nuclear" grenades. and of course haircuts and uniforms

Iron Eagle, this 16 year old kid steals an F-16 and gets into a dog fight. I lost count of how many AIM-9 missiles were fired from the same wing-tip launch point. Problem is, you have two wing-tips and two AIM-9's mounted there, that's it. I saw this movie with a bunch of my AMMO troops and we laughed our asses off watching that flick.

TV program, MASH. The whole concept, uniforms (haircuts), and general disregard for military discipline and courtesy. I still enjoy watching it.

War is no joke. TV and movies are to entertain us. Even so called factual movies and TV stories are full of nonsense. Take it for what it is and stay informed. Hogan's heroes is one of the best examples made. The Germans were very cruel to prisoners. They and the Russians killed or murdered hundreds of thousands.

In the "sword and sandal" flics, like "Gladiator" I go nuts when I see the Romans (or any other ancient troops) riding horses with saddles and STIRRUPS! A company will spend millions on authentic looking sets, costumes and equipment—then blow it on something so lame. I thought the show that came closest to getting things right was HBO's "Rome."

The rampant fraternization between men and women in the same unit and between soldiers of superior rank with their subordinates. The almost total disregard of military customs and courtesies between subordinates and superiors and the lack of consequences for violations of orders and regulations. A major offenders is the CW's "Valor". which is more like a Melrose Place or Riverdale in uniform than a military themed drama.

The final scene in The Green Beret, where John Wayne and the Viet Nameese boy stand watching the setting sun over the South China Sea, which is east of Da Nang.

Screwed-up uniforms and medals/ribbons. Worst movie about Vietnam I ever saw was about the final days of the 24th Evacuation Hospital. Supposedly just before it closed (advertised as a true story - it wasn't). I was one of the last three officers there and the movie was wrong.
