Recently I’ve been doing reasearch on APC’s. I found the Pandur II to be a good choice to be added to the German tech tree as either a premium or a Marketplace vehicle. It’s armament is as follows:
Main armament: 30 mm Mk44 Bushmaster II gun or 105 mm Cockerill high-pressure gun.
Secondary armament: 7.62 mm FN MAG machine gun or M2 Browning heavy machine gun. For balancing reasons I would say the FN MAG would be the better choice, seeing as the M2 absolutely shreds. Next to coaxial machineguns it can also carry the following ATGMs:
Spike LR anti-tank guided missile or the TOW anti-tank guided missile. Seeing as both the TOW and the Spike are already included ingame, it should be no problem integrating them.
All in all, I see the Pandur II fit a similar role to the Marder series in the German tech tree, albeit a bit newer, so I would say it could fit at either BR 7.7, 8.0 or 8.7.
Here’s an image of the Pandur II in the Czech army.
