At least some, if not the majority of the 500 Marmon-Herrington Ford 4x4 COE conversions, delivered to Russia under Lend-Lease from late 1941 to 1942, were used to carry BM-13-16 "Katiusha" Rocket Launchers, probably the first foreign chassis with the BM-13 installed on.
The drawings are based on several war-time photos, where the shown vehicle is incorrectly described as »GMC COE« or »Chevrolet COE«.
