The Churchill Kangaroo was an APC variant of the Churchill tank. For this purpose the turret was dropped and the opening closed. The Kangaroo concept proved to be very successful and was first used by the Canadians who used obsolete M7 Priest‘s. It was then quickly adopted by the Brits.
Inside of the Churchill Kangaroo is room for a driver, a machine gun operator and four soldiers. The armor protection and climb ability is clearly superior to the regular M3 half-track, the overall speed is significantly lower though. There are also variants that have the additional armor. That makes the Churchill Kangaroo even more durable and gives you the opportunity to transport infantry savely even through heavy enemy fire.
To recornize the vehicle. The Churchill ARV and Kangaroo are the same models. Only the Churchill ARV is equiped with tools and cables and the Kangaroo not.
