It had the same 105mm main gun as the M60 and M1 Slick, but was equipped with an autoloader which left it with a 3-man crew. Like the Sheridan it was designed to be transportable in a C-130. One of the neat features I thought would make it especially for an assymetric/OOTW type operation is that it had three bolt on armor "suites" which allowed the level of armor protection to be upgraded in theater according to the conditions on the ground.
As light as it is (20 tons), it's probably well suited to the jungles of Thailand.
