This is part of SF training since at least the 1970s. During the 1990s the military built an entire Bosnia village at Ft Poke and even flew in native Bosnian speakers to time play in their native language for us small teams guys getting ready to go to Eagle Base in Herzegovina. People need to get a grip this is normal small teams work.
We trained in Vietnamese villages at Polk in 1970. It helped when we got in country.
