IamA son of Ukrainian army soldier, who spent three moths on front line, while he is on vacation he can answer almost any question AMA!
Father doesn't speak English at all, and my English is far from perfect, so we are sorry for our language:)
EDIT0: thank you guys, it is a bit late in Ukraine now (3 AM) so we need a rest, we will answer the rest of questions tomorrow morning (if any)
EDIT1: we are back, will continue answering
EDIT2: thanks for everybody, my father went back to front line, so we are not able to answer your questions anymore
