The CTMS-1TB1, also known as the Dutch Three Man Tank, was a larger version of Marmon-Herrington's CTM-3TBD. Built for the Netherlands Purchasing Committee for use in the Dutch East Indies, the vehicle was considered unsuitable for US use due to poor reliability, insufficient armament, and lack of power. Some were delivered to Dutch troops in Surinam as well as to some Central American countries.
