The T14 and T16 were designed by Marmon-Herrington for foreign contracts, but 240 were accepted by the United States in 1941-2 when the Japanese overran the intended users in China and the Dutch East Indies. Designated the CTLS-4TAC and CTLS-4TAY by the manufacturer, the tanks differed by which side of the hull on which the turret was mounted. The CTLS-4TAY (designated T14 in US service) had the turret offset to the left and the CTLS-4TAC (called T16 by the US Army) had the opposite arrangement. The turret rotated through 240°, and the driver sat beside the turret in an armored hood with vision blocks around him. Besides the 240 accepted by the US, around 105 were successfully sent overseas and at least one shipload was sunk in the Pacific.
