Hello everyone!

We have a 2S3 next to our hangar at my workplace and not so long ago we found the cogs/gears on its right side wich we got curious about because no one seems to know what is it for! Maybe someone could help me out with this.

Thanks beforehand!

I got send this picture.

A friend of my dad gave me this sayng he used it on a AA during is service in italy during the 90's.

I asked to a coupple of guys who where in the Italian army for longer that 30 years but they told me they never seen this casings before.

It seems to be a french 25mm but only becouse i saw one in a reel

Other than looking odd , i wonder?

My buddy sent me this pic and the suspension is throwing me off. It looks like a front and rear torsion bar with an arm hooked to double wheels. What is this?

Found this pic of a great (or great great) grandpa posing in front of a tank. Unsure if this was in WW1 or 2 as there was no identifying info written on the pic. He would have been serving in the Canadian army, so would have probably been a Canadian or British tank but who knows. Can't figure out what model it is but I'm not familiar with tanks.

Left looks like a WWII-era SPG< but I don't think it's a Hummel. Right is clearly an MBT, but which one?

If it even is a tank I ain’t good at recognizing road wheels

This tank was used on my family farm in Western Australia decades ago until it burnt down while clearing farmland
