In progress according to some reports (which I do not necessarily believe or dis-believe).

A group on nine 'Ukrainians' were smushed recently on the front.  There were five Polaks and the other 4 were of undetermined nationality.  Seems that the so-called 'AFU' are sucking fumes in the 'Ukrainian' tank and have flipped the fuel tank selector.

In another story, Poles resented being sent East to face the Russians and wished to remain among the living for their main mission.  That is, be pre-positioned around and about former Ukraine in order to exploit the inevitable partition of the place.  The hard-core Bandera Ukrainian's job is to guard the rear and kill normal Ukroid conscripts and such who try to escape the front line.  Tensions between the Poles and the Nazis actually resulted in a skirmish with fatalities.  Pretty funny if true, and from what I can see it's completely possible if not likely.
