Is there a more accurate DI portrayal in a movie than Full Metal Jacket?

The story i heard about RLE and that scene was that he was just supposed to be a consultant for the actor that was supposed be playing the role. Ermey started doing his thing to demonstrate and Kubrick said hey let's film this.

he was also secluded from the rest of the cast, so when he made his first appearance it really was his first time meeting all the "recruits"
