Firepower
Same firepower as the 2A5. The only difference is that it gets DM11, which is even worse than HEAT or standard HE since the only way to kill anything with DM11 is a direct hit which is near impossible if you use the LRF. DM11 is useless against both aircraft and ground targets so what’s the point of adding it?
Armour
There is no option for the frontal add-on armour package to replace the dozer. Leopard 2PSO has the same hull as the 2A6EX demo 2 which also has the mounted frontal armour.

Leopard 2A6EX DEMO 2 shown in picture above with mounted armour package
Last time I checked RPG-7 wielding terrorist are not present in 10.7-11.7 (or any other BR for that matter) which makes the side armour just dead weight.
Additionally, the side armour and dozer are fixed, so you can’t even remove it for more mobility.
Correction: Dozer is now optional but not the composite side screens. Armour does not replace the dozer when unequipped
An argument could be made that the PSO never mounted the frontal armour package. …but then again, neither did the M6A2E1.
Mobility
The PSO adds 7.5 tons and 150 HP 130 HP to the 2A5
2A5: 1500/59.5 = 25.2 hp/t
2A6: 1500/59.9 = 25.0 hp/t
2PSO: 1650/67.0 = 24.6 hp/t
Correction: 2PSO bug reported to be 1630/67.0 = 24.3 hp/t
The PSO still has worse power-to-weight ratio than 2A5 and the 2A6, with no tradeoff. The Strv122s have 24 hp/t, but they have the frontal armour package + Roof armour.
Extra
Same thermals as 2A5, gen 1 gunner, gen 2 commander. Some say it should have better thermals, so may it may change before release.
Correction: No evidence found for upgraded thermals on PSO
Lastly, so far Gaijin didn’t even bother to give the PSO it’s distinct historical demonstration camouflage.
Conclusion
Why was the leopard 2PSO added now? It brings absolutely nothing new to the German tree, if anything, it should have been added as a premium/event or TT 2 years ago. No upgraded thermals. Barely any better armour. Not even a new Camo. In it’s current form, Germany waited 3 years just for a side-grade 2A5.
