This set features 3/5 Cavalry AFVs that fought in the Vietnam War. 7 M113A1 ACAVs and 3 M551 Sheridans. All of which featured visually interesting and striking markings, coupled with fine stencilings (that seems mandatory on all vehicles). Notice that each vehicle has a yellow shape with red number on both sides of the hull. Triangle denotes A Troop. B Troop uses a square/rectangle. While C Troop, a circle. This set allows both types of vehicles to be featured in one diorama, since all are Black Knight vehicles! Also provided: full, accurate exterior M551 hull stencilings & silver-edged Data Plates (for the AN/VSS-3 searchlight), accurate M113 exterior hull stencilings, and Vietnam era .50 Cal ammo box stencils. The Vietnam war M551s are full of stencils, particularly the turret sides and rear. When you remove any of the ammo boxes or water can, there will be a stencil visible. When you remove a tool from the hull rear, so will a stencil appear on the surface beneath the tool.
