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

Off the top of my head, the upside-down SSG rank / shoulder boards of Channing Tatum's character in "Dear John".

Next is the classic scene in Rambo when he fires the LAW inside the helicopted but the backblast doesn't injure the POWs or damage the helicopter's interior.

In an episode of Two and a Half Men, after Jake joins the Army, he somehow has the 3ID right shoulder patch on his uniform after graduating basic and AIT.

The newest Fast And Furious movie has the "Heroes" chasing a submerged Soviet Alpha Submarine being operated by remote control across the ice at about 90 mph to stop it from launching it's Nuclear missiles. 1) Top speed of a submerged Alpha is about 40 knots. 2) No sub ever made can be controlled remotely! Period!. 3) The Alpha class is a fast attack sub! ALPHA'S CAN NOT CARRY NUCLEAR MISSLES!!!
I don't expect perfection in action adventure movies but come on! do a little research please!!!

hair is always to long

On several counts, it's the closing sunset scene in John Wayne's "The Green Berets"...never knew the sun to set in the east!

My biggest disappointment, SSG Pete Fleming, was not having my own personal Jeannie, like Major Nelson did, waiting for me at home...

Behind Enemy Lines. Gene Hackman is an Admiral dealing with "rogue" pilot and his go to guy is a MCPO. Where is the COS, Air Wing CDR, Squadron CO? In other words, the rest of the Chain of Command.

Also, probably already said, but Under Siege and the scene where the Phalanx system (anti-missle) is used to shoot down a jet plane flying parallel with the ship. TOTAL BS!

the list is never ending and the part I never understand is how they do it so consistently about relatively recent military actions such as Vietnam or WW2

Seriously getting a Roman war movie wrong (and they are almost ALL horribly wrong) is a bit understandable given no Roman grunts are around to protest the mistakes but stuff from the last 60 odd years of history? Hollywood simply does not care.

Some Europeans do well though think Winter War re; Finns vs Russ. But the US still makes crap like Fury....

I can tell you which movie I feel came closest to getting it right. Two of them, band of brothers got the group dynamics of a deployment spot on and Stripes perfectly depicted the thought processes of your average private down to the shitstorm their stupid decisions make. They both have problems and misrepresentations usually for comedic or dramatic effect, but their the best.

For me it's a tie...In the movie "Commando" Colonel Matrix (played by Arnold Schwarzeneggar) places several Claymore anti-personnel mines alongside a barracks type building, and when he sets them off the entire 4 story building blows up from inside, nothing left but matchsticks. And in the movie "First Blood 2" John Rambo (played by Sylvester Stallone) fires a LAW rocket from inside a helicopter filled with POW's he just rescued from a North Vietnamese camp, and there is no backblast and everyone is perfectly OK. (And in various scenes, the rocket actually switches back and forth between a RPG to a LAW and then back to an RPG).

In Top Gun were Maverick said "I could tell you, but I'd have to kill you".
