Two pics from Hungary 1944: SS-Jagdverbände, and in the background - a Nimrod AA Tank!
The first picture (guys with Panzerfausts and Nimrod in the back) is really interesting for several reasons:
1, It is the courtyard of the Hungarian Museum of Military History (and also Military Archives). It used to be barracks, though I am not sure if that was still its function in 1944. The Nimrod you see in the background was IIRC unoperational and was used for demonstration purposes at the time of the SS commando operation, but they used it as some kind of deterrant aiming its gun at the entrence. When the Tigers appeared it very wisely raised its gun barrel to signal it does not wish to enter the ring.
Thanks to that, it still exists, it survived the war by some miracle and was restored in the recent years. AFAIK it is now displayed in the exact same spot in the Museum's courtyard as on the picture!!
2, If you look in the background, upper left of the picture, you can see a very unique weapon of WW2 (white boxed with dark circles on them): the Hungarian LŐTAK anti tank mines. These were set up on the side of the roads leading up the Royal Castle Hill. IIRC the mines were relying on cumulative (HEAT) effect and would attacked the side of the tanks passing by. They were however removed from the roads after negotiations between the Hungarian garrison and the Germans.

I was thinking and possible they have written "Mérgező" on the tank, though in this case they have a very ugly handwriting
It would mean "Poisonous" - which would probably make the most sense, perhaps a warning to soldiers that some chemical or biohazard was present.
