| Notes | The Ram was a Canadian cruiser tank based on the chassis of the US M3 tank. It had a lower silhouette than the M3 and had a new turret capably of 360° traverse. The Mk. I was armed with a 2 pdr Gun and had an auxiliary turret plus side doors, these were omitted on the Mk. II, which was also up-gunned with a 6 pdr. Mainly used for training, the Ram saw action as an OP/Command Tank. The Ram chassis was used for a number of conversions, mainly self-propelled artillery (Sexton Mk. I) and armoured personnel carriers (Ram kangaroo). |
