Known as the "Americal Division", some of the 1-1 Cavalry M113A1s that saw action in Vietnam. Early vehicles had interesting names / slogans on the sides, but did not come with serials or bumper codes. One interesting M125 Mortar Carrier is also featured in this set. This unit is uniquely identified by "squarish" colored rear corner on both sides of the hull. Red for A coy, White for B coy, Yellow for C coy and Blue for HQ. The "squares" are often different sized from vehicle to vehicle.
