The Churchill I/II’s armament was a 2-pdr gun in the turret with a co-axial machine gun and a 3-inch howitzer or 7.92-mm machine-gun in the hull (The version with the hull mounted machine-gun is usually referred to as a Mark II).
There were also some versions with two 3-inch Howitzers and others with the 2-pdr and 3-inch guns swapped over.
The 2pdr armament proved inadequate from experience in the desert and in March 1942 a model armed with the excellent new 6-pdr gun was released (Churchill III).
In 15mm scale they are suitable for Flames of War or any other game played in 15mm.
