Hi Nail ,Welcome to Armorama
# 1: The left side needs a bit of work . This is a M1 that Animal is working on

The white plastic card is added to get the turret face to the right shape . I did a post in Rvt. Review on this step by step but I deleated the pics to make room . If you need them let me know
# 2 : MMMMmmm I dont mess with P E much sorry
# 3 : Turret APU - I see a lot of those in the pics so I think it is ok to go ahead and put it on
# 4 : combat loads - Ammo - or crew gear ? All ammo would be inside the tank - 40 rounds I think . 120 mm ammo has a combustable shell so the crew keeps it under cover . Crew gear - depends on the units load plan . The purpose of a load plan is so that if another crew has to use my tank all the critical gear is in the same place as it is on every tank . The standard issue per crew man is : 1 Alice pack - 1 CVC/helmet bag - 1 sleeping bag w/ cover - NOTE - these are in the new Tamiya kits - they look great - 1 NBC suit bag 2 duffle bags -( I know I left something out ) So just take all this x 4 and you have a lot of gear to add to the tank
# 5 : I'll have to look around a bit on that one - there were a lot of good tank names on TV Here is the link to Archer ,They ship pretty quick lots of OIF options
