The plot involved three pilots, I believe a white guy, white girl, and black guy, belonging to the same team/force being deployed to an area and being unable to leave because their mechs are damaged. A local woman has a valuable artifact that looks like a circuit board with a large hemispherical pearl on it. She ends up selling it in order to buy the team weapons for their mechs they use to win and escape. The mechs are mechwarrior-style cockpits on legs, not humanoid. The people are live-action and the mech combat is 90s-style CGI. One of the weapons is a solid red laser beam. The title might have started with an A.
Might you be thinking of Gunhed (1989)...?
In a cyberpunk future, Kyron-5 supercomputer attempts to exterminate the human race, but Gunhed mechs stop it. In 2038, five thieves break into a condemned island facility to steal Kyron's dead CPU. The place turns out to be a deathtrap.
According to the synopsis, five people venture onto an island to steal a CPU, but the three most prominently positioned on the movie poster -- along with a large mech -- are an Asian man, a white woman, and a black man.
