Phantom Raiders (1988)

Miles O'Keeffe teaches old flabby Vietnam vets some ninjitsu and then they go after the commies in Rambo style, only with exploding throwing stars. There's almost no dialogue after the first few scenes, just: run, shoot, run, shoot, run... The interior scenes are under-lit, there's no real character development, the plot is thin and the action scenes aren't particularly interesting or well done.
