A unit of Ukrainian officer cadets was recently sent to the Donetsk region, in the east of the country, to help reinforce the border, after Russia annexed Crimea earlier this month.
One of those - Maxim Garmash - was born in the area.
And with many of the people in the region supporting Russia, he found the cadets were far from welcome.
