Ah yes the M20. almost forgot.
-The M20 is basically a greyhound without the turret, just a browning LMG up top.
-Can upgrade it's armor with sideskirts for increased durability.
-Crew comes armed with a bazooka.
-Can lay AT mines
-Vet lets it pop smoke on itself to escape.
As far as it's role it is a bit like the 221, but it has a bunch of stuff that lets it be useful in a variety of situations.
Rather flexible, and good for assault. Something interesting - all vehicles have manpower upkeep, right? When an American tank crew leaves its tank, does the overall manpower upkeep change to that of the squad? In other words, if i am starved for manpower and i have a small company of tanks, can i simply abandon all the vehicles for a while to get a small boost in manpower income? Having control over abandoning vehicles is a powerful tool.
Got ahead of myself there, it will be a feature i will find out over time.
