Can anyone identify this tank?

I think your confusion is caused by it missing the sloped superstructure pieces on the rear hull.
I, certainly, thought it was all a roofed superstructure but after a little looking found the rear is not roofed and the two sloped sections are just "Walls".

Your picture is the tenth of weasel's first link (the tank has both german and soviet markings - and the caption claims it is a soviet Jgpzr IV L/70 destroyed in Hungary.

Scorpio_Rocks,

The caption translation you quote is not quite accurate - it's all in the suffixes, a very fine distinction.  If it said "Красной Армии", then it would mean "(belonging) to the Red Army".  As it is, "Красной Армией" it means "(some action) by the Red Army".  So in full the caption says (as close to the original wording) "Destroyed by the Red Army SGC Jagdpanzer IV L/70 from an unknown unit. Hungary. German self-propelled gun carriage Jagdpanzer IV L/70.

Just to clear things a little.
