Notes: Some Swiss M-113A2s are fitted with a dozer blade in the front. The blade is as wide as the vehicle and one meter high. Frontal hits are 50% likely to hit the blade, which has an armor value of 10. The blade unbalances the vehicle and interferes with the trim vane, robbing the vehicle of its amphibious capability.

Notes: Some Swiss M-113s are fitted with a one-man 20mm autocannon turret similar to that found on the Swedish Pbv-302. These vehicles are almost always fitted with appliqué armor on the hull front and sides; the front appliqué is a simple steel plate, while the side appliqué is ribbed steel plates providing the equivalent of spaced armor.
