Or the Sd.Kfz 234 series of the WWII era, which apparently got the Puma nickname somewhere along the way, though as far as I know the Germans never actually called it that.Correct. About the only thing they share is the name 'Puma'.

Where all of them built? Did they enter service? If not, why?

None of them were built beyond a couple of prototypes. This was an export design that never found customers.
It was intended for the Bundeswehr as well. The end of the Cold War and the so-called 'Peace Dividend', not to mention German Reunification costs & general worldwide economic dislocation, clobbered the program unfortunately.

Of which variants were these prototypes built?
Several countries uses doors on their ifvs, so there must be some tradeoff to using doors over ramps.After operating the M113 for so long, I can't imagine why the German's would go to such an awkward 'troop door' arrangement, as opposed to a ramp! If anything, I thought this was one of the BMP-1 & BMP-2 recognised design faults....

Yeah, I've operated from both door and ramp mate and I know which I prefer - time of mounting and dismounting, getting gear and weapons systems (ATGM, Mortar's) in and out, ......Several countries uses doors on their ifvs, so there must be some tradeoff to using doors over ramps.After operating the M113 for so long, I can't imagine why the German's would go to such an awkward 'troop door' arrangement, as opposed to a ramp!

My guess would be that doors are smaller, therefore lighter for the same amount of protection. That might make it possible for troops to open & close side-hinged single doors by hand without needing to lift a couple of square metres of metal. It's possible that whoever wrote the requirements had decided that placing reliance on power to close a ramp door was, for some reason, unacceptable.Yeah, I've operated from both door and ramp mate and I know which I prefer - time of mounting and dismounting, getting gear and weapons systems (ATGM, Mortar's) in and out, ......Several countries uses doors on their ifvs, so there must be some tradeoff to using doors over ramps.After operating the M113 for so long, I can't imagine why the German's would go to such an awkward 'troop door' arrangement, as opposed to a ramp!

This is a picture, not just a line drawing, so apparently something actually built.And the last image of the prototypes corresponds to a Puma 4 prototype that was equipped with a Leopard 1 tower and with a strange cannon or similar for tests.

Those doors are almost as bad as the failed Canadian Bobcat APC of the 1950s. This sort of "economy" is used by engineers when the "poor bloody infantry" end up "priority last" in the design process.Beancounter logic in action?
Im not 100% sure but it looks similar to concepts of a 35mm anti-helicopter vehicle i have seen. I cant find the source right now but if i remember correctly it was part of the Kampfwagen-90 plan before the anti-helicopter and anti-tank role were merged into a giraffe tank.That IFV HELPAK version is interesting. I don't recognize the turret. 35MM?
