We get to find a video of a milsim event that took place in Thailand last 24 May 2015. Called the Black Sheep 2015 Milsim Ops, the venue wasn't disclosed but it looks like an abandoned big commercial building. It's the first trailer of the event as posted by Sirasin Sremaroeng. Check the 1:00 mark, someone still had time to take a selfie. :)
