Dutch was with the 101 airborne or Delta if i am not mistaken according to the book and scripts/movie (the picture on the lighter that Dillon was showing off and Blain/Mac shared), though he could have been a Green Beret as well. BUT him and his unit were an elite Special Ops Army unit in ALL of the scripts. Anti-Terrorism & Rescue was their specialty in the 3 different versions of Predator aka Hunter & the movie tie in book that I have read. Jim Hopper/ J.S. Davis, the Green Beret that was killed was his closest friend. They had went through boot camp and such together.
