Changing the American Tank Destroyer Tree

MrVic: Hehe Ontos the black sheep of the US armed forces. Prototyped I think in the 1955? Was built and run through its paces, then was summarily rejected by all branches of the armed forces. Then in desperation for air lift able tank the US Marine Corps order about 300 due to there being no other option. Its greatest perk was ability to travel about anywhere due to light weight. Draw backs were the 106mm guns only had 18 rounds for all 6 guns total. 3/16" thick armor floor so mines were their bane. The back blast from the recoilless rifles were so large that their location was given away instantly combined with if any friendly troops were remotely near its rear they were killed. The big killer was a crew member had to climb outside the tank to load it... Also it had a tendency to fire prematurely. Its greatest use was a AT gun in a fortified position and improvised to be used for anti infantry which it preformed well at
It was well like by the troops and deemed very useful in Vietnam but overall well ehh
Be a fun Premium not sure I want to level through one tho
