AMBT

In the early 1970s, the project was proposed by Captain Timothy R. O'Neill, a Project Officer of Army Armor and Engineer Board at Fort Knox. It was supposed to decrease the vehicle's size and weight to the detriment of its armor. Mobile and stealthy vehicles were considered to counteract anti-tank weapons of that time more effectively. It was planned to use solutions from German Leopards, as well as parts and components of M60 tanks of various modifications. No prototypes were built.
