The M25 Tank Transporter (G160) was a combination 6x6 M26 armored heavy tank transporter/tank recovery tractor and companion 40-ton M15 trailer introduced into US Army service in Europe in 1944–45. Manufactured by Pacific Car & Foundry Co., it was a substantial upgrade over the Diamond T M19 transporter/trailer duo introduced in 1940. Nicknamed the Dragon Wagon, it was replaced by the 10 ton 6x6 M123 semi-tractor beginning in 1955.
