Ostpreußen Heer P.007d-128m
"Super Speed Battlefield Taxi 2.0"
The most advanced iteration of the P.007 series of combat vehicles in Ostpreußen inventory, with new APS systems and armor covering the MBT.

Turret
The new Mk7 turret provides a significant upgrade over the prior Mk2 turret with significantly stronger armor and crew protection, at roughly the same size and mounting the same offensive weapon.
The new Rh-128A2 smoothbore rifle is capable of firing APDSFS and HEATFS at higher velocities than the Rh-128A1, at the unfortunate cost of slightly worse accuracy over long ranges.
The gun does have the advantage of being slightly lighter, made specifically to fit in a smaller turret interior, while still keeping its offensive capability.
The turret protection is well over 1000mm against APDSFS and HEATFS thanks to the mixture of Titanium panels, RHA, composite ceramic and lamented glass, and a special and secretive gelatin mix that fills the space between the armor panels in the turret cheeks. The side of the turret, while not as armored, has similar values to the face of the Mk2 turret, thanks to the NERA and composite ceramic/laminated glass slabs mounted to and embedded in the turret.
The last passive defensive measure for the turret is the new APS known as the AMS-2 "Haferkönig", a set of optical columns on the roof and two laser hemispheres intended to detonate HEATFS shells before they impact the turret or hull. While it has a 72.61% detonation rate of HEATFS shells in trials and tests, it's still hoped that any shells that impact are negated by the NERA and composite armor.
Much like the Mk2 turret, the crew has access to a variety of cameras. The commander and gunner have access to the sighted optics offset on the left of the gun barrel, as well as the Commander's SITREP column that's near the rear of the turret. While the loader doesn't have access to much more than the SITREP optics, he does have access to a roof-mounted MG15 15mm cannon thats on a 360° swivel mount. Lastly, the driver has access to the SITREP optics, as well as a rear-facing camera embedded into the passenger compartment door, so he'll be able to see what's behind the MBT when stationary or reversing.

Armor
While the turret got a significant upgrade thanks to the Mk7, the hull got a reasonable upgrade in protection with a number of slat skirts on the sides, and a composite ceramic/laminated glass skirt on the very front of the chassis. While the upgrades have their best interests in mind, there were no noticeable improvements made to the chassis itself -save for making the entire hull out of steel instead of a steel-aluminum mix as seen in the c(U)- which typically leaves the engine and driver in a somewhat vulnerable state.

Versatility
Much like every P.007 before the P.007d, the hull is very capable of amphibious actions with little setup, all while carrying 5 passengers in the aft-most compartment. Though, due to the added weight of the new turret, add-on armor, and the steel composition of the entire vehicle compared to prior versions, the hull has a lower amphibious endurance compared to prior versions.

an unrelated note;
The majority of P.007 MBT series of combat vehicles are considered Main Battle Tanks in the Ostpreußen military, while outside they'd very readily be considered wheeled Tank Destroyers. Either way, they both fill the same role of knocking out hostile armor.
