I don't know about other countries, but for Poland, I think that I'm right. Soldiers weren't in 80s totally interested in any ideological indocrination. Why? Because it all was contradictionary to their personal experience, and what they would see in the West would give them even more proof how bad their polish living condition and the system is. This period as I stated above, the Poles knew what was in their country and what was in the West (some idealized views, but we all could agree that there was much more consumer goods). 80s and also early 90s has a big part in developing polish national complexes towards the West. So it is like in my short tale, in Poland Andrzej could buy only vodka which was rattioned, in Kaufland he could saw many kinds of liquors in fancy bottles. It is a common thrope, that in 80s western consoomer goods were seen as better and more atractive than local, and nice packing was a part of that. People here even collected empty beer cans, and displayed them on MDF wall units among other trinkets, because that was something. Because polish industry didn't provide beers in cans, it was "western" it was "better". And in Germany there weren't lines for bread. Like visible on

I don't see any reason why polish soldier could have very big ressentment against the western population. Ok, maybe some against Germans, because they weren't popular, that's pretty obvious.
Billions of years of racist tropes and nationalism

You don't know much to what were soviet soldiers capable in the history, to what excesses. Germans were also capable during the 2ww, and any other soldiers too if you loose their lashes. The most important is that you need orders to commit the greatest crimes, or upper aproving of loosing discipline for common excesses (just like the soviets during ocupation of Germany, when they raped, pillaged and looted whatever they could seize, hating of germans for ocupation is one reason for that, but other is that the commanders allowed it). The "nazis" didn't need much indoctrination, because it wasn't like you think that they all the time in all places just shot to whoever they saw. Even in Poland, they massacred one village in my regions, and in the village two villages further common german soldier from the construction battalion on the airfield had deals and good terms with local peasants, those soldiers were older men (in 40s), and there were situations like from Allo Allo. Example when one half of my greatgrandfather shack was seized for quaters for germans, and in the barn were partizans. There were horrors and comic situations which happened for the same people in short time, like sometime later, my greatgrandmother and maternal grandmother (who was little at the time) miracously avoided death in some german punitive action after death of a german soldier (they returned home from visiting family in another village).
The most important, soldiers who would fight in 80s, they were born in 60s, they didn't remember the war, they don't have personal grudges against Germans or even Soviets. They have totally diffrent mindset that people from 40s or 50s.
I can say as always, that a knowledge of the outside world and opinnion of their own system, was wastly diffrent for Poles and Soviets in 80s. For Poles "the war for the peace" wasn't their own war. I agree that in the WarPac weren't any issues of rivalries between states, because all was totally subjugated and controled by the Soviet Empire. The Polish People's Army was the most sovietived structure in Poland, I mean commanding officers and military secret service. I agree also that the GDR was one of the most indoctrinated and loyal states in the camp. Which cannot be said about the Polish People's Republic, especially in 80s when this country just rooted.
