The best 2.5k fighters within the Warsaw Guerillas become Aegis Guards (Marauders with the powerful Aegis Barriers)
The rest of the 39k Polish freedom fighters become Starcraft Marines
Polish pilots and crew get to operate 20 Siege Tanks, 10 Diamonbacks, 4 Goliaths, 70 Wraiths and 12 Helions
10k non-combatant Warsaw women become Starcraft Medics having the abilities of both I/Brood War and II
One Polish civilian gets Tychus' gear while another gets Raynor's equipment from SC2
They have cybernetic implants that allow them to use Stimpak without negative side-effects AND give them the knowledge to use their new 'toys'
300 Predators/Cybercats appear BUT they only kill Axis troops NOT Soviet troops
47 of the Polish civilians know how to make more of the various Starcraft tech in this scenario as well as any basic prerequisite Real Life tech
Obviously this makes it much easier for the Allies to win WW2 but it does affect Poland's future and the Cold War after
They do have limited ammo, Stimpack, energy, etc. Just not surr how much though. Still, they would be killing enough Nazis to loot enough weapons and WW2 ammo when SC tech starts to break down or ran out of stuff
Not sure how this affects Poland during the Cold War or how the advanced Terran change everything
