I did not think marines used the M1 Abrams I have never seen a marine operate one. and they better get the f-35 JSF as a model it replaces the ageing harrier so it would be really cool to have a hovering plane thats stealth and blowing things up. there are 3 versions of the f-35 one for the air force to replace the f-16 one for the nave built a little bigger and can make carrier landings for the navy and one for the marines to replace the harrier it is stealthy can fly mach 1 and produces less heat.
