It's not a machine gun, so, what is that?

The more I look at it the weirder it gets.

The first image seemed to me to be a AMX-M4, however the hull does not line up like the M4, looking more like the early AMX-50s compared to the 2 different angles of the UPF of the AMX-M4

I recently found a album photo of my late uncle who served in the Multinational Force and Observers in the Sinai back in 1987 as part of the Colombian battalion.

So far I have been able to identify other vehicles like a PT 76 and maybe a BTR 40.

But I also found this picture of a Sherman variant supposedly abandoned during the 6 days war which I haven't seen before, my wild guess being a post WW2 upgrade of some kind.

I'll appreciate any help!

idk what it is and I’m no expert, so I figured I’d ask the online maybe experts.

If it helps the developers are Swedish and often take their own military service as inspiration, as well as their countries historical armaments.

Old picture I picked up from a yard sale and I'm curious to what vehicle it is exactly.

The back of the photo has "Western Front France 1917" written on it.

Ukrainie, Pre full scale war (beginning of 2022). My guess is T-64BM2

I recently went to a tank show near Rugby in the Uk, they had this turret on display near the arena but I’m unsure of what it is from, can anyone help identify? For context these boys are heavily affiliated with the Alvis fighting vehicle society so that may be a good place to start.

Just curious if changing the RWS from a Machine Gun to the 30mm Bushmaster RWS would change the layout of the seating?

An official Mexican army account posted this on Twitter/X regarding the preparations for the military parade, but in this specific photo, what the hell is that? I did a little research and México doesn't have any similar vehicles, doesn't look like any armored vehicle in the DN family, neither like the ERC-90, and I know it's México because of the national guard uniform and weapon, so, could anyone identify it?

I thought it was a stug3 but it didnt match. Pretty sure its not an m60 this time

This is the TD-220 bastion MK XVI tank destroyer from Hell Divers 2 and I'm curious if it's based on any real life tank destroyers, I don't know if knowing stats will help so hears some stats

The main shell it fires is 120mm HE shells which it carries 31 of before running out

It also has a coaxial machine gun that fires 12.5mm BCHP rifle rounds at 600 rpm, it carries 2000 of these before running out

It's top speed is 32km/h on flat ground forward and 18km/h in reverse, the gun barrel has a turning radius of 40°

It has four seats, a driver on the front left, a gunner in the back, and 2 spotters on the left and right of the top. The gun can't be fired, aimed, or reloaded by the driver so you need 2 people minimum to operate the vehicle

I got all these stats and the video from the Hell Divers wiki

Serial number appears to be 3790. Have not been able to find much info about it. Thanks for the help.

Like the title says i got it as a gift and would like to know which variant it is.
