80's / 90's Guerilla/ horror/erotic movie

Hi,


In advance, I apologize for my English 


I have a vague memory of a few scenes from a film that I kind of saw when i was kid.

the action took place in the jungle, it seems to me.
A group of westerners find themselves attacked, trapped by the military / local militia.

The first scene that shocked me at the time: one of the female victims was raped by the barrel of a gun 
and inevitably the executioner finished it by pressing the trigger

the second scene is prettier: a female militia officer having sex with or raping one of the female victims.

I am aware of the little information I give here, and I have already searched the net to find this film

I do believe the film is CAT CHASER (1989).

Like  I said, the film took place in the jungle. Maybe Vietnam

Opposing Force also known as Hell Camp (1986) with Lisa Eichorn and Tom Skerrit, perhaps?
