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

It the last Rambo movie the clay-more mine exploded like a nuclear blast.

Saluting at random and the never ending bullets. Just two of many.

My personal pet peeve is grenades that take 20 seconds to blow. The worst example I ever saw was that Die Hard movie about the airport. Bruce Willis is in the cockpit of some military plane, and the bad guys start lobbing grenades into the cockpit, but they don't blow up until after Willis has time to strap himself into the ejection seat and eject, at which point all the grenades go off simultaneously.

When they need to find the ignition key.

A Few Good Men...Col Nathan Jessup is explaining the erotic sensation of having sex with a more senior officer, but laments that "since I'm A Colonel, until they elect some gal President, I'll have to wait". Wow.

How about talking on a sound powered phone while holding it to your ear with your shoulder.....hmmm

The use of "Roger, over and out" on radios irritates me. What that means in communications is, "Roger, I understand. Over, invitation to respond. And Out, end of conversation. " So, I acknowledge your last, I am waiting for your next transmission, but I am through with this radio call."

When watching a 'war' movie my wife's most used expression is "What did you see now?" when I rewind and pause the video to verify a goof e.g., uniform errors, troops too close together, nuclear hand grenades, et cetera ad infinitum, ad nauseum.

Every watch Walker Texas Ranger? All the years he's been on tv Chuck Norris has never dropped a magazine and reloaded.

I don't remember the movie, but they had F-4 Phantoms, in a Korea vintage movie.
