Updated East German file and a scenario for Nienburg, "WM_WGEG Weser Line" are attached here.
To install, just extract the "FPRS" folder into your Modules.
Remember to back-up your "Common" folder in FPRS/Data, as it substitutes it with my copy.
I made quite a few changes to the East German file, so I don't remember each one. Some off the top of my head...
-Mot-Schützen Regiment (PzD) renamed MSR-9, and the battalion specifically.
-Mot-Schützen Regiment (SPW) has had it's SPAT Company (Three platoons of SPW-40P2 armed with either PALR or PTUR) replaced with a static AT Company (Two battieries of T-12)
-Mot-Schützen Battalion (Spz BMP) re-structured: Every third "Mot-Schutzen" subunit is now an "RPG-7" Subunit, support section was re-structured, and each company has at least one Mot-Schuetzen subunit armed with a sniper rifle. The AA platoon has also once again been detached from the Kompanie into it's own unit a-la the Soviets.
Regiments once again operate the 3 MSB/1 PzB or 3 PzB/1 MSB formula again
Timeframe restriction removed from T-54
Added Flak Kanone Regiment to Divisional assets - these replace the SAM regiment in mobilized (reserve) divisions.
2S4 Tyulpan and 2S5 Giatsint restricted to the new "Soviet Support assets" tab; these units aren't owned by East Germany but provided by the Soviet AAG.
Big nerf to the T-72s: TG-20 (Firing more modern Soviet BM-32 and BK-21 125mm rounds) has been replaced universally by TG-17 (Firing the BM-15, the most advanced round provided to Warsaw Pact client states) they should be struggling against NATO MBTs now without flank shots or close combat.
Divisional recon battalion restructured: Two companies each containing a radar platoon of BRM-1K, two tracked platoons of BMP-1 (Carrying Scouts instead of Mot-Schützen), and two sections of SPW-40P2 carrying scouts
Divisional independent tank battalion replaced (As it seems none existed in the NVA) with Reserve recon battalion: Two companies each containing two platoons of PT-76B, and two sections of SPW-40P2 carrying scouts
WM_WGEG Weser Line

I had trouble balancing this one and it looks like balancing is still required in the future.
As the title suggests, this is a medium scenario between the two Germany's, meant to be played from the East German side. While playing against the West German AI is possible, it's not preferable as, in my opinion, the defensive AI is rather lacking and I don't imagine we'll see a more complex trigger/scripting system until Southern Storm. Instead, you can play it in Hot Seat or PBEM mode, and the West German player will follow a set of instructions in their briefing.
Here, 19. MSD is behind schedule and making an assault towards Nienburg in order to capture the Weser river bridges here. As part of a mobilization division, much of it's equipment is old, including vaunted T-54 tanks that, while unable to stand up to modern enemy armor, are still effective against a tank's traditional prey.
Panzerbrigade 3 has successfully evacuated the stricken Clauswitz-Kaserne, and is on the defense; it is well armed with Marder 1A2 and Leopard 2A4 tanks. This scenario is about speed and how fast the assaulting East German player can reach his objectives.
The story here is divorced from my discontinued East German campaign, so don't concern yourself too much with any plot holes between them.
Finally, I eventually plan to create a NATO version of this scenario that does not require any fancy scripting behaviour as the AI's offensive decision-making capabilities are sufficient. It will also swap out the East Germans for the Soviets.
Good luck and have fun!
