#ukraine bored with computergames, go to Ukraine to play real war
these kind of kids go around in Russian Occupied zone to shoot at gas stations and the like
and we have also Russian journalists, western extreme rightwing tourists and Russian militias coming over to have some fun, try to storm something or fire some guns or tanks or artillery
the same happened during the Bosnian war and for more Muslim-inspired bored youngsters there is ISIS now
by the way, you can get killed by the Ukranian army (as a few hundred to thousand Russian families have experienced) - even if you are a socalled professional soldier and you go into Ukraine because you get a lot of money - and your family even more (relative) if you get killed (but don't get wounded).
