homoerotic

If you consider locker rooms, barracks, and other places where men are in various states of undress to be "erotic" then any realistic film about military trainees, athletes, or others who are in situations where they use common facilities to change clothes, shower, etc. will seem "erotic".

There were a few scenes where homosexuality was strongly implied -
When the smallest, frailest, most boyish guy in the platoon gets sent to report, alone, to the Sgt in the weapons shed, and the Sgt gets his kicks by beating him up, it's probable that there was a rape as well as a beating.

The scene where Paxton and Bozz take the two girls to Bozz's hotel room, and after the sex is over, are more interested in talking with each other (while naked) than in paying any attention to the girls suggests that women are not that important - either due to chauvenism, latent homosexuality, or the simple fact that females in 1971 did not share the same relationship with the military and Vietnam that males did.

In this film, young men have to deal with emotional issues relating to other young men, while in a "macho" environment. Simple acts of friendship or human compassion can easily be interpreted as being "soft", "pussy", or "gay" in those situations, but violence and hostility are acceptably manly - which is one of the reasons that the hostility and violence tend to get out of control - as happens int his film.
