There was a movie I watched when I was a kid. It was a movie about a military or a group of people that used mechs to fight with. I say it in the late 80 early 90. I remember one fight scean where one of the mechs shots out as a wepon. If anyone has any ideas to what this movie could be I would be vary happy. Also the bad mech was black I think

Thanks

Sounds a lot like Robot Jox.
