Hi, for years I've been searching for the name of this particular movie. Watched it in the early 80's. It's a martial arts movie. Its about ex army guys getting a call from the head guy who's in a wheel chair. They go out and find the bad guys. One of the guys name is Duke. Don't recall if that's the leader of the good guys or vice versa. That's all I can remember. I loved this movie I know don't have much info but if anyone can help!

More info about this movie... it was about ex-military who were in vietnam(I think) they came across a mine field and the squad leader decides to go first... he ends up stepping on it... the movie cuts to several years later and the squad leader is now in a wheelchair. He calls up all his ex-squad members cause he wants to find out who killed his wife. So there's the first scene, they're at a rodeo and there's a guy and a girl boinking in a barn and one of the cowboys is an ex-member. One was a construction worker and there's a fight at a construction site. One was a banker and there was a fight in the parking lot, the guy was like, "you guys want to play - I don't have a glove. One guy was a pimp and he fights another pimp on his turf. One was a mechanic or something like that in a shop. Anyway, it turns out the ex-squad leader is not actually in a wheelchair and he ends up killing all his buddies cause he wanted revenge for what happened to him in Vietnam. At the last scene he says he suffered, so he wants everyone else to suffer. The ex-leader is always dressed in black like a ninja.

Sounds like it might be Kill Squad from 1981.
