Page "Assault gun" Paragraph 10

British and American forces also deployed vehicles designed for a close support role, but these were conventional tanks whose only significant modification was the replacement of the main gun with a howitzer.

Among these was the M4 ( 105 ), a M4 Sherman tank armed with a M4 105 mm howitzer.

In addition, the Mark IV version of the Centaur tank and the Mark V and the Mark VIII versions of the Churchill tank were fitted with 95 mm howitzers.

As the amount of German armour encountered by the Allies decreased, especially in Italy, a number of American tank destroyer units were used in the assault gun role for infantry support.
