M6 3″ (75 mm) anti-tank gun and M198 155 mm howitzer, Lewis Army Base, Joint Base Lewis-McChord. The M6 was an anti-tank gun derived from the main gun of the M24 Chaffee light tank, and the M198 is a towed artillery piece used by the Army and Marine Corps, although it is being phased out by the newer M777.
