The one in the far distance in the upper left might be a Panzer Elefant(Sd.Kfz. 184):

Knocked-out tank destroyer "Elefant" -official designation: Panzerjäger Tiger (P) "Elefant"- during Operation Zitadelle, July 1943.

[PzLdr]

Ferdinand Porsche’s biggest [in all senses] mistake. Turretless tank [actually an assault gun] with no machine guns to defend the vehicle. Only weapon was the 88.

Contributed greatly to the failure of the northern wing at Kursk. The Russians chewed them up snd spit them out. I think only about 80 were made. What a waste.
