Acquired by the US Marine Corps, the CTL-6 was an iteration of Marmon-Herrington's CTL-3 with a new engine and vertical volute spring suspension bogies akin to those found on the light tank M2. The new powerplant forced the engine decking to change to a horizontal profile from the earlier sloped arrangement. The engine louvres were .25" (.64cm) thick.
