This is absolutely the result of sloppy map-making on my part, but I'd just like to point out that the Gandvian 2nd Division along the River Bug is supposed to be heavily attacking the Nibelung 2nd Panzeraufklärungs Brigade, aiming to overrun its positions or force it back, rather than engaging in a more limited holding effort. Not that this is necessarily occurring, of course, but that would be the Gandvian intent.
While it really seems like something I should have changed earlier, I think your assessment of the Pav.84 as carrying a less-potent main armament than the Fafnir 2A6, anyway, is fair. Though it's based more on the Leclerc than the T-90, and is supposed to have been designed much more according to Western than Soviet principles, the Pav.84 is still most likely inferior, overall, in terms of protection, and its gun, while maybe somewhat close to the Rheinmetall L44, is most likely outperformed by the L55. The Gandvian response, I suppose, will probably be to try and counter the Fafnir's better gun with gun-launched ATGMs, and wherever possible try to hit them with laser-guided shells and heavy mortar bombs.
One more small point before I forget, I noticed that I mentioned 48 self-propelled howitzers in the opening attack post, but that actually should refer to 105mm self-propelled howitzers only. Out of laziness, I counted all the 152mm guns, towed and self-propelled, together.
Be back soon with some ideas for Ranalte!
