Ettore says the base model is the Tamiya M1025, converted into a Special Forces Dumvee using the Pro Art Models conversion set "US Special Forces Dumvee".
He added some scratch built parts like the ammo boxes rack on the turret, the radio rack, the folded camo cover on the roof and nets in the rear doors.
AT-4's are from Legend Productions.
For reference Ettore used various threads on www.armorama.com, photos on www.primeportal.net and books like "Special Forces In Iraq". He also used a couple of photobucket albums
