This POTD is of two Canadian Sherman tanks in the Netherlands during the final year of WWII. This is a somewhat unusual pairing in that one is a Firefly and the other is a 105mm howitzer equipped Sherman. The crews of both tanks seem to have fully committed to the idea of spare tracks as effective add-on armor. The Firefly crew has gone so far as to attach what looks like track from a Panzer IV on their turret. All in all, a very cool photo.

Edit: A reader named “Whelmy” has pointed out that the Canadian “dry pin” track looks very similar to German style track and could very well be the track around the Firefly turret. As far as we can tell, the Canadian dry pin track (CDP) was not generally used as track on Canadian Sherman tanks, but was used on Canadian vehicles based on the Grizzly (a Canadian version of the Sherman) such as the Sexton SPG. CDP was not interchangeable with American style track since it had a narrower pitch, which required a 17 teeth drive sprocket.
