The Ram II* Tank was a Canadian cruiser tank developed during the Second World War. It was based on the chassis of the American M3 Medium tank, but with a new turret that could mount the British 6-pounder gun. The Ram II was designed to replace the Valentine infantry tank, which was considered inadequate for Canadian needs. The first prototype was completed in November 1941, and serial production began shortly after. However, the Ram II was never used in combat as a gun tank, because it was inferior to the American M4 Sherman in terms of armament and protection. The Ram II was only used for training purposes in Britain until mid-1944, and some of its chassis were converted into other roles, such as flamethrower tanks, observation posts and armoured personnel carriers.

It was introduced in Update 1.61 "Road to Glory". The M4A5 is quite a hybrid of traits from the British and American ground forces trees. The Ram is made up of the transmission, suspension, and engine from the American M3 Lee, the turret platform of an M4 Sherman, and the British 6-pounder gun. Thus, in its place in Rank 2, the play style is akin to the M3 Lee's mobility with the power of a turreted tank. It should then be played like any standard American medium tank, with extra caution on the weak points presented on the front armour right next to the front machine gun turret.

;US Designation*

The Ram II was a Canadian tank that was based on the American M3 Medium Tank chassis. The US Army identified it as the M4A5, but it was not a M4 Sherman variant. They used a system to name tanks by engine and hull. The Ram II had the same engine (A1/A4) and cast hull (A1), so it got the next available M4 number: M4A5. However, this designation was not widely used and the tank was usually referred to as the Ram II or simply the Ram.
