I haven't so far been able to find any mention the Russians simulated tactical nuking of Poland during the excercise
There was none, they were having an excersize on how to invade Poland (Poland was dubbed as an agressor) tests of nuclear bombers and launches of missiles capable of carrying nuclear warheads but no actual simulations of nuking.
Well, that's a far cry from excercising nuclear attacks on a NATO member...
Meh this is just a propaganda show coupled with actual combat testing of what junk they still have, no one in Poland cares that much and rightly so.
Great! Then you have some and France has some and GB has some...only poor little Germany has nothing! NO FAIR!!! *wails*
Its not 100% certain that you dont have them and you can develop them in approx half a year (by comparison Poland would require about 2 years).
