SD:M3 Scout

 is a United States Transport unit.

Overview
The White Motor Company created the M3 Scout Car in 1937, with 6.4mm of face-hardened armor, four wheel drive, a four speed transmission, and power brakes. The design was used widely until 1943, when it was replaced in service by the better armed, protected, and mobile M8 Greyhound and M20 Utility Cars, but remained in service with Allied forces via Lend Lease. A number of countries continued to use the M3 well into the 1960s.
