Poles who initiated it, Serbians who were military elite to it and Ukrainians who rightfully, same as rest of us, belong in it.
Ho-ho-ho... You have supplied a good laugh here Crow!
I regret to inform you, that the days of Winged Hussars, Janisseries, and Sich Cossacks has long since passed.
During the most recent Strong Europe Tank Challenge, Poland and Ukraine came last and second-to-last respectively (1st place Austria, Germany 2nd, US 3rd, and France 4th). Serbia did not participate unfortunately, but something makes me think they would join their Slavic brothers at the bottom of the list. Interestingly, Poland was bested by Ukraine despite Poland using the very non-Kosher Leopard 2s (albeit old ones), while the Ukrainians were using T-64 Bulats.

If only the competition was in rakia, horilka, or wodka consumption - there, truly, this Slavic trio would be ahead of the entire planet...
Today these armies are only good as soil fertilizer in the cauldrons of Donbass (Ilovaisk), or as NATO bombing practice.
