the one already existing looks a bit more accurate
curiosly see there is another T-34/76 listed and that actually has a correct tracks chassis with the Christine suspensions and no spacer wheels on top ...
so this one could be regrouped too

with this

another merge/delete thing

and some more military vehicles

we could take the vehicle on the left as mentioned by JB

and this I am REALLY REALLY sure it's made for movie , doesn't match anything , has NO headlights and I haven't a single real one without headlights and blink lights (as they need to be street legal) and was put thru some abuse in the movie , likely based on something like a Ford F 350 chassis

to further my point notice even full military vehicles like the Striker APC have headlights and blink lights...

or the M2 Brandley also with blink and headlights
