SD:T30 HMC

 is a United States Support unit.

Overview
Another of the M3 half-track conversions created by the White Motor Company, the T30 Howitzer Motor Carriage was the result of marrying the versatile M1 Pack Howitzer on a modified half-track. Introduced into service in 1942, 500 were produced and remained in use until the 1950s.

This particular T30 has been modified for use in a direct-fire role, as fire support for other units.
