The scout car M4 was based on the Ford/Marmon-Herrington 1.5-ton commercial truck, and was considered inferior to the scout car M2A1. The M4 was manufactured for the National Guard, but may have used soft steel instead of armor plate. Note that not all sources list the vehicle as becoming standardized, so its prototype designation of T13 may be appropriate.
