Lee,
Your Abrams is looking good so far.
I bought this kit for a fellow modeler 3-4 months ago, and it looked really good in the box.
Please be aware that this builds the original M1A2 version that came out in the early '90s. It doesn't have the A/C Vapor Compression Unit in the Bustle Rack, the Armored Conduits that run under the Turret Rear for the A/C Unit, nor the Under Armor Auxiliary Power Unit (UAAPU) inside the left rear Hull Sponson (where the Fuel Cell was located on the earlier versions). (pictures from Prime Portal's M1 Abrams page

VCU Armored Conduits:

UAAPU (access plates on top of the hull, 4-bolt plate on side of hull, triangle exhaust port on rear of hull next to taillight housing):


Unfortunately, this version did NOT serve in Iraq, as the M1A2s that deployed after the initial invasion (and I think all other M1A2s) had already been upgraded to M1A2 System Enhancement Program (SEP) version.
If you build it as provided in the kit, IIRC a 3-tone NATO Camo pattern would be appropriate for either a unit in Continental U.S. (CONUS) or U.S. Army Europe (USAEUR).
I hope this helps, and I look forward to seeing how your build progresses.
Happy New Year!
