The Half-Track was introduced by White in 1940. These were military vehicles that combined front-wheel steering with tracks on the rear axle, giving them excellent capability to operate in difficult terrain. Notable models include the M2 Half-Track Car for reconnaissance and light transport and the M3 Half-Track Personnel Carrier, designed to transport troops (up to 12 soldiers) and used as a general support vehicle. The Half-Track were powered by a 6.3L inline six engine with a 4-speed manual transmission and rear track drive. They were lightly armored and could be armed with Browning machine guns (.30 and .50 cal) mounted on circular mounts or rails. The modular design allowed for multiple uses: ambulances, rocket launchers, anti-aircraft guns, and command posts. The Half-Track was essential to the Allied forces, especially on the European and North African fronts, and remained in service in several countries even after the conflict. Its combination of mobility, versatility, and cargo capacity made it one of the U.S. Army's most successful tactical vehicles in the war. The White Half-Track was produced until 1944.
