@IAMAL_PHARIUS @sickburnbro @nugger you're mixing up a lot of things. When they asked Germany for tanks first it was the Leopoard ONE, which were decomissioned already at that point. Not the Leopard 2 for which you posted the chart of who bought it. (Leopard 2 transfer came after and had less delays)
The PUMA from that article is the German infantry fighting vehicle, like a Bradley, and it is notorious for being high-maintenance, much worse than the Leopard.
