Draft. And that's what makes it so weird - nationalistic Western Ukrainian warhawks are running from the draft like Belgians (), while ethnically Russian guys from Ukrainian - controlled parts of Donetskaya and Luganskaya oblasts go and fight for their country.
My spin on this observation: Western Ukrainians haven't seen the war as being on their doorstep yet, and so have little motivation to fight. The people of the war-ravaged region however have seen the Russians destroy their homes, the homes of their neighbors, the homes of their friends - and they want to fight back.
Funny how it's the other way around, actually. Rebels have so far incurred incalculably less collateral damage than Ukrainian forces, and this is reflected by the sheer number of photos and videos of destroyed civilian homes being posted by each side. Besides, even the people from oblasts untouched by war, as long as they are not in Western Ukraine, go and fight with almost no draft dodging. Only the most rabidly nationalistic Western Ukrainians run.
@Mr. Strange: Oh, they are not being persecuted - this war has nothing to do with ethnicity. Neither they need to be pro-Ukrainian or anti-Russian to not avoid the draft. It's all in the Slavic mentality, you see - when you get a call to fight for your country, you shut up and do it period, as evidenced by all the people from Central Ukraine, which will not be attacked by the rebels, whose repeatedly stated goal is only to get the Ukrainian Army out of Donetskaya and Luganskaya oblasts, also not dodging the draft. Only the Western Ukraine, where the support of Ukrainian nationalism is the strongest, had large numbers of would-be conscripts literally running for their lives. Oftentimes, into Russia.
@Baffler: I am sorry, I don't get what you are talking about.
