| Notes | The British concept of Infantry tanks was continued right through WW2, the Matilda I was built along these lines as a slow moving heavily armoured vehicle, it had a cast turret housing a single machine gun and a crew of two. Fifty were taken to France with the BEF and none came back, those remaining back in Britain never saw action. |
