Alexander Sotkin, 24, has been posting selfies to Instagram.
People do that everyday, what's the big deal?!
Well, he's pictured in combat settings like military encampments and he appears to have activated a locator map that shows where his pictures were snapped - inside eastern Ukraine earlier this month.
On Monday he posted shots located back to the rebel-controlled Donetsk, where Flight MH17's wreckage was found.
