Also as I said in my original post, it is from F troop, 3 ACR, most likely the Troop XOs tank.
Tamiya has markings for two tanks from F troop in their 1/35 M1A2 kit, the markings are for tank 23 and tank 43 (options A and B).
They are:
A: M1A2 of 2nd Platoon, F Company, 2nd Battalion, 3rd Armored Cavalry Regiment, Iraq, April 2003.
B: M1A2 of 4th Platoon, F Company, 2nd Battalion, 3rd Armored Cavalry Regiment, Iraq, April 2003.

The XOs tank (FX) would have the right side bumper number of F65, as opposed to F 23 or F 43 on the right side. The left side would be lll on top, with 2/3 CAV below it. You can see these on the Tamiya decal sheet for the same kit, on the right side about in the middle of the sheet.

The same three black stripes would be around the bore evacuator as well. These denote the 3rd Troop (F Troop) of 2nd Squardon.
I can't make out what is on the barrel though.
