So I have been set on a path into the military for some time now and I'm highly interested in becoming an Armored Crewman for the Abrams tank. I've sat in tanks before and I have an above-average knowledge of armored warfare, how tank ammo works, maintenance, etc. There are a few things I'm worried about however: am I too big to fit in one? (I'm currently 6'2") Can I sign on immediately after basic or do I have to qualify for something? What's it like being in one and what are the most common threats? Can I choose what crew position I want? (Loader, Driver, etc.) Any other details are welcome. Thank you!
