I couldn't give you a 7.5, so I gave you an 8. I was an M1 and M1A1 crewman for 4 years, and you got a LOT right. Looks to me like you were in, too. One thing you didn't do is open the doghouse (the site for the gunner in front of the commander). The mud effects are in the right spots, too. Takes skill to pull that off right.
