It looks good and he did a really nice job overall. A couple issues though. First, it is an early M1A1 with the cover on the primary sight box having a sloping rear (looks like the Tamiya ODS kit) but the gear, especially MRE boxes and sleeping bag stuff sacks (from newer Tamiya US Modern Accessory set, 2000s), are more modern. Also, it is a US Army tank (IDed by the smoke grenade launchers), but the crewman laying on the front slope is wearing a USMC 8-point hat and the leaning guy is wearing a modern USMC body armor vest. Lastly, what is the guy standing on the bank throwing?
It looks like he used this crew set (with some switched heads/hats), which is totally wrong for this tank.
