Hi, Ghosts!

Want to ask a small question about Unidad soldier model.

There is a cool-looking enemy in this trailer https://www.youtube.com/watch?v=1QUccFa1jlc (0.58 minute) with a black beret. I don't see this kind of enemy in a full game.

Was is cut off from the final build?

Or we can see this type of soldier in specific mission?

I have visited large military bases such as MOB Condor and Jaguar, but didn't find this type of enemy.

Thanks!
