Hey Chief,
well, I'm a little late on this one but Bill is correctthe tank belongs to 1st TBN 1st marine division, delta co. (probably 3rd plt judjing by the three stripes of the 'monster energy M' but there is more than one company in afghanistan...
the PSM set supplies you with a bit more than what you'll need (e.g. the AN/VLQ-8 MCD and turret roof armor)
for the tank you want to depict you'll have to use the belly armor, late style TI phone, FO/AC antennas, BFT antenna, 50 cal. camera, belly armor, umbrella stand, gunner's shield, DUKE antennae USMC style smoke dischargers and the BRE from the PSM set

...and probably lots of 50 cal ammo boxes (again, check psm for that)
Djiti prod from france also have a great commander's figure for a-stan tanks

send me a pm if you have any more questions regarding Afghanistan M1's

Cheers, Max
