Ping for critique.
In fact these photos were discussed numerous times on this forum. Maybe one in a hundred E. Ukrainian ‘terrorist’ looks any like a military regular. Most of these people are in their 40s which in not typical for Russian military, who are usually around 20 yo and even special forces are well under 30.
There might be some Russian presense but the majority of people are locals or Crimeans, probably ex-military who came to support the locals.
