The model shown is an old Airfix M113 ACAV kit in 1/76 scale. The former JB Models sprues should normally be smaller than other 1/72 scale kits, but it is barely noticable. I added a lot of detail and stowage, mostly resin from Legend Productions.
The front shows the added smoke dischargers (normally they look a bit different, but those were the only ones I had spare to add some at all) and the red cross decals I took from another kit (Revell HMMWV Maxi Ambulance I think?!)
A closer look at the side reveals the crew tent, an ice box and CIP panel.
MRE (Meals Ready to Eat), CIP panel and even more tents, back packs etc. Operation Iraqi Freedom vehicles were covered with tons of personal items.
