What film best captures what being in the military is truly like?

Honestly I can’t think of any movie that’s accurate because I always see a few things wrong and it bugs me for the rest of the movie. So i can’t decide which is the most accurate. I can name the least accurate movies portraying the military.

Heart Break Ridge and Full metal Jacket.

Although the Marine Corps supported Eastwood's production of Heartbreak Ridge, they must have really chuckled of putting one over on the real heroes of Grenada: the the Army Rangers! So I find it hard to recommend this film as an accurate portrait.

Platoon

We were Soldiers....

hacksaw ridge ; about medic in the wwII in the south pacific saving a lot of men. also won MOH

Back when they came out, I thought that MASH was a hoot, but felt that Catch 22 was far more real. Exponentially surreal as it is, Apocalypse Now has got to be the greatest flick of all, IMO. The horror.

Too many variables to choose one movie. Marines or Air Force? Officer or Enlisted? Combat, support, or administrative?

Most of the titles listed, like "All Quiet on the Western Front", "The Longest Day", "Full Metal Jacket", and "MASH" - even "Catch 22" - do a good job of capturing certain aspects of the Military in combat (and there others, too numerous to list or even remember). But, as someone else mentioned, a movie that tried to capture a completely comprehensive account of the entire Military "experience" would probably put you to sleep.

Full Metal Jacket. Almost thought I was back in boot camp.

There is no film (movie i.e.) that has ever or can ever truly capture military life.
