Why? The G11 in the V1 timeline was the main service rifle for the West Germans. The G41 was the supporting services rifle. Both production lines would have been in place and operating concurrently.

Standardisation was clearly NOT a priority for the Germans otherwise they wouldn't have even begun to consider the G11 and it's caseless ammo. Given that it was set to enter service in 1990-91, the Germans would have had 4-5 years to build up a war stockpile of ammo, plus whatever else they produced once production was ramped up in advance of hostilities. Until the production facilities were destroyed, probably by nukes in late 97 (although likely attacked conventionally numerous times prior to that), there seems little need for the Germans, with their separate logistical train to the US, British, etc, to conform.

Also, the G11 was developed because a soldier could carry more than twice the ammo as an M16 armed man for the same weight, had better accuracy, and was much more controllable - why throw that all away for the ability to share magazines with soldiers who are operating in a completely different area?

I agree that the East Germans would continue to use their pre-unification equipment (although perhaps with new uniforms and vehicle markings) - there's little doubt that the west would be totally unable to re-equip them all in just a few weeks or months (depending on the version timeline).

Granted it may not have been Pact doctrine to not combine depleted units, but that's the situation we're faced with in the game. To me it's quite simple to explain it - the units were in constant action in the beginning, under pressure all the time. The opportunity simply wasn't there to withdraw units form the line and reorganise them in any significant way. Later in the war, the logistical ability to shift large numbers of troops and equipment around had disappeared.
