Oh gosh, those were just regular wheels huh. No cogs.

Uhm, yes? The road wheels on a tracked vehicle typically aren't cogs, only the wheel actually powering the track is a "cog".

Uhhhhmmmmmm. lol.

Yes, I was thinking of that powering cogwheel. But I realize, the little raised wheel there is probably the back of the tank, eh. Not the front driving wheel, which is probably a cogwheel out of frame.

But yeah, the wheel with the cogs isn't called a "cog", it's a "cogwheel", with "cogs". The cogs are the little "teeth". 👍

Just in case you're interested, I believe the vehicle pictured is a Vickers Universal Carrier which has the driving cogwheels located at the rear:

Ah, there we go! Thanks for digging that up for me 😊 Okay cool, so I assume that means the engine is also close there, further in the back?
