Lancaster War zone video

trying to figure out what this is what it says who it represents . . . and I will show you how I search Google images with the image cropped and find nothing similar nowhere near it. I wonder what? because it represents a group a military group that are not sanctioned as a military recognized by a certain government or country. it's like the call and sign up again and that's exactly what they're speaking about in this video. I'll put a link to the original video so you can see the whole thing for yourself. thank you for watching
