I don't remember the particulars of what happened on the Eastern Front being taught in my high school history classes. The Canadian military was concentrated on the Western Front, so what little detail was covered was concentrated there as well.
Also, when I was in high school, the Ukraine was not an independent nation, but part of the USSR—I don't think our classes even mentioned it had ever been separate. Actually, I'm not sure it was even once mentioned by name. This would be the case for the majority of the MPs as well, as I expect more of them than not were born before 1980.
