the problem with Kaliningrad is that it surround.
Russia only has the 11th Corp station there.
2 Motorized Rifle BDEs
1 marine BDE
1 Self propelled Field Artillery BDE
3 ADA BDEs
1 Missile BDE
80 Tanks, 240 IFV.
the most black sea fleet is located there. also about 2 fighter Squadrons
the problem is that most of the remaining Western Front ground forces are just as far from there as most of nato forces. not to mention they would have to invade and take the baltic 1st. which means they would have to leave forces there to hold those.
the three combined Baltic nations have
2 Mech BDEs???, 9 Infantry BDEs if you they fully mob. (no tanks, no IFV). but the baltics are great for defense. forest, swamps, and urban areas. are great for light Defensive forces.
Poland (counting Reserves) forces taking Kaliningrad.
2 Cav BDEs, 2 Tank BDEs, 3 Mech BDEs, 14 Infantry BDEs, 1 CAB, 2 ADA BDEs. there also 1 US Armored BDE CBT TM in Poland.

the French army, Spain, Italy, Rom, Hungary, UK, US and other NATO ground forces would be overwhelming in numbers. not to mention Air units.
the naval in balance would be even greater. if Russian forces were dumb enough to move out on the offensive or counter attack NATO they would be punished. the smart move would be to fight a defensive war. but even then that would be stacked against them.
