Right now the M2A1 Slammer is OVER POWERED because it can carry 48 rounds (120mm HE+AP) AND passengers AT THE SAME TIME.

The turret is intended to have space for about 10 rounds while the back can function as storage for palleted ammo or as passenger transport but not both as the space used is the same.

The game should have either two versions of the vehicle or a tweakable one to achieve this:
*10 rounds of 120mm + passengers
*48 rounds but no passengers
