Identification for tank

Now, we’ve all seen this image

many many times. With that said, I never noticed the tank in the background (far left). What tank do you guys think it is? It has the main gun of a 75mm M8 Scott, but there is another turret on the back. Give me your identification guesses!

Its an AK-47

Its an LVT(A)-5 viewed from the back.

I would agree with the M8 guess, but the hull looks more like a LVT than a Stuart. So my final guess is the LVT(A)(4)

Also, I don’t really see a secondary turret, are you talking about the black thing on the top? If so, then that looks like it could be a MG mount

or, what pancake said. I did not see the replies, lol

This is quite possibly it. Good find, and thanks!
