I'm trying to remember which movies contain the following scenes: 1: Chuck Norris impales somebody with a bayonet on a machine gun, then fires the grenade launcher (something like an M-203) on the gun, which blows the body off of the bayonet and out a window. Then, the grenade and the guy explode outside the building. Maybe one of the Missing in Action movies? 2. Which Dirty Harry movie had the radio control car with the bomb attached to it chasing Callahan around in his car? Thanks for your help. I'm confident someone will know the answer to these.
