| Notes | Based on the M3 chassis and built by White, the M15 mounted a 37mm automatic canon and twin water cooled .50 cal M2 Heavy Machine Guns on the M42 mount and could deliver devastating fire not only at aircraft but ground targets. The side armour could be lowered to allow for this mode of fire. The M15 was issued to armoured units and saw action in the Mediterranean, Northern Europe and the Pacific theatre and served in the Korean War. |
