Okay, I'd like to address a few points on Kraków with the caveat that I haven't read the rule section thoroughly so far and only skimmed over Karlsborg. I also get that the publishers try to keep the background light, probably because it's an alternate history setting where everybody has (sometimes strong) opinions about and it's hard to please a community so diverse as this one. So my thoughts are meant to add meat to the bones in order to make T2K's Kraków feel more realistically and fit into 1990s Poland better.
First of all, 1990s Poland was historically and will definitely be in T2K (I'd argue) anti-communist. In Poland, and many other post-communist countries, this meant shedding all communist institutions from the state or at least renaming them. This makes it very unlikely any such institutions would be around in 2000, and ORMO - the name of Kraków's people's militia in T2K - is such an institution that was despised heavily. ORMO stands for "Ochotnicza Rezerwa Milicji Obywatelskiej" and means Volunteer Reserve of the Citizens' Militia. In other words, it's not a regular police force, but a volunteer militia. It was also used to beat down protestors, such as strikes. ORMO failed as an institution during the 80s and was dissolved in 1989. So, ORMO was out of the picture, even before communism was gone or the USSR had collapsed.
This makes it very unlikely that a Krakovian militia would be named ORMO, unless Kraków is firmly in the hands of neo-communists, which it isn't in T2K. Since Kraków is a free city with traditions to Polish independence and national pride (to say the least), it's much more likely that any (semi-)volunteer defense organization active there would have ties to another institution originating in communist Poland, the Territorial Defense Forces (Obrona Terytorium Kraju; OTK).
OTK was originally an internal security army and separate from the army. Founded in 1965, OTK included Internal Defense Forces (Wojska Obrony Wewnętrznej; WOW), being the largest part, and smaller territorial defense battalions. OTK was also responsible for transporting Soviet forces and supplies through Poland during wartime. While the organization was reorganized after the fall of communism and became somewhat obscure in real history, being disbanded in 2008, a successor organiziation was formed in 2017. The new Territorial Defence Force (Wojska Obrony Terytorialnej; WOT) is something that T2K's OTK could have developed into, given the persistent Soviet threat looming over Poland in the alternate 1990s.
OTK would then have remained or again have become a volunteer force of territorial defense units, probably heavily intertwined with semi-official stay-behind-units like the historical Home Army (Armia Krajowa; AK) of World War Two. These territorial defense forces are common in Northern and Eastern European countries and were only disbanded in post-Cold War Europe because of the peace dividend.
The difference between OTK and ORMO is that ORMO was despised, OTK was not. Also, OTK actually existed during the 1990s, while ORMO was disbanded before the final days of communism.
A second point is the way Kraków used to work in the 1990s. Kraków is home to two major football clubs, MKS Cracovia and Wisła Kraków. Both were and are inimical to each other, but during the 1990s they also had bloody street battles, were heavily politicized, with Wisła leaning towards the political nationalist-right with strong notions of antisemitism while Cracovia is leaning more into the left, also having ties to Jewish clubs historically. Also, Wisła fans with their nation pride also were not only strongly anti-communist, but often saw themselves as successors to the AK, the World War Two underground army that fought against Nazi and Soviet occupation until the 1950s.
Both clubs also had fan communities that had ties into the criminal underworld and black markets, with Wisła ultras (die-hard fans) being called Wisła Sharks and controlling the criminal underworld of Kraków and Poland to a certain degree. They even took on a police SWAT unit once and didn't actually loose.
So, in my opinion, if anyone runs the black markets of Kraków and that city is truly non-aligned, it would be the Sharks and certainly not the Russian vory (called Vorovskoy Mir in UO). The Sharks with their nationalist political mindset would also have ties into the security apparatus, especially militia structures such as the OTK.
In other words: Football (soccer for some
) and militias would be the back-bone of Kraków politics and security, not something called ORMO and Russian thugs. Those would have to tread very lightly in a post-invasion Poland. The country isn't actually Russiophile, not even Polish communists were.
