LVTH-6 (Landing Vehicle, Tracked, Howitzer) - with M49 105 mm howitzer

The M46/47 Patton was an American medium tank designed to replace the M26 Pershing and M4 Sherman. It was one of the U.S Army's principal medium tanks of the early Cold War, with models in service from 1949 until the mid-1950s. It was not widely used by U.S. Cold War allies, being exported only to Belgium, and only in small numbers to train crews on the upcoming M47 Patton.

The M46 was the first tank to be named after General George S. Patton Jr., commander of the U.S. Third Army during World War II and one of the earliest American advocates for the use of tanks in battle.

M46 (with & without sand-shields, late muzzle brake, MG, searchlight)

M46 is a rebuilt Pershing with a new engine deck/rear hull.
M47 is a revised M46 with a new turret and hull front. (Only Pershing bits left are the wheels...)
M47M with 105mm will be included with M48, since it shares that vehicle's engine deck.
