Ostpreußen Heer P.007c(Upgrade)-50m (Urban)
"I'm not sure if it's an IFV, APC, MICV, or APF"
The newest support AIFV in Ostpreußen inventory, the P.007c(U)-50m (Urban) is a direct upgrade in near every way from the original P.007a-50m (Urban).

Turret
The specialty developed Mk3 turret comes with a variety of offensive and defensive attributes. Containing a respectable level of frontal spaced and composite armor, as well as an integrated ATGM Launcher on the right face of the turret, it's a very capable offensive extension of the existing P.007 hull.
The primary weapon of the Mk3 turret is the Rh-50A1 autocannon, a rapid fire 50mm gun with a choice of HVAP or HE belts to devastate unaware armored vehicles and infantry alike.
The secondary weapon is the GM50 Missile mounted in a retractable pod built into the right side of the turret. It's capable of opening up at request of the gunner and/or commander, fire off the missile at enemy armor, then retract safely behind the composite plates mounted to the ATGM pod.
To backup the offensive firepower, the spaced armor in the cheeks of the turret are able to withstand most HEAT and HEATFS shells lobbed towards it, while being able to glance APFSDS Sabot rounds at extreme angles.
Though, the biggest issue for enemy gunners is managing to hit a flat surface, as very few flat faces exist on the front of the turret. Through testing, it's been discovered the turret face can resist upwards of 550mm of penetrating HEATFS, and roughly 310mm of APFSDS.
To add to this, a large blowout panel exists on the roof of the turret, and several composite blocks of armor are placed on the sides of the turret.
Finally, the newest Ostpreußen APS is mounted to the roof (red towers) and turret sides (red hemispheres), the AMS-2 "Haferkönig". It's capable of knocking out or disabling most ATGMs coming for the AIFV, and protect the crews from an unfortunate end.

Armor/Hull
The hull is that of the P.007c(U), being also mounted onto the P.007c(U)-128m.
As stated there, the frontal upper plate has protection againt HEATFS rounds of 700mm, while APFSDS is around 575mm-600mm of protection in weaker, less sloped areas.
The lower frontal plate, while respectable, leaves a bit to be desired. Protection from HEATFS to upwards of 500mm, while APFSDS is closer to 200mm of protection.
The side composite slabs on the hull do provide an equivalent 500mm of HEATFS protection, and an impressive 675mm of APFSDS protection.
While the P.007c(U)-50m (Urban) does have very respectable armor all across the board, it's main goal is to be a support AIFV to the MBT P.007c(U)-128m, being capable of indirectly guiding missiles over cover into enemy vehicles and fortified positions that the P.007c(U)-128m wouldn't be able to engage normally.
As such, crews are trained to stay with infantry, or within short-range radio distance of a P.007c(U)-128m, to be as effective as possible in the AIFV role

Versatility/Mobility
Since the hull is of the wheeled P.007 series, it's very capable of amphibious actions with very little setup needed.
Add to the increased 5 passenger capacity, it's able to carry a squad of infantry or similar troops to a frontline beach if necessary, and provide excellent infantry support with it's equipment.
Not to mention it's guide-by-wire GM50 is capable of firing over most obstacles and disable or destroy difficult hostiles.
Much like the P.007c(U)-128m, the commander and gunner of the AIFV have access to Thermal and IR scopes to identify hostile vehicles or infantry at night and/or low visibility situations, while the loader has access to the roof-mounted 13mm autocannon.
Finally, the P.007c(U)-50m has access to a smoke launcher system integrated into the turret cheeks and mantle, capable of hiding heat and thermal signatures from ATGM weapons, as well a Thermal balloon to assist with redirecting heat-seeking weapons.
