the coordination not that big a deal. the USAF special operation helo guys train with all the army and navy and marine operators during workups. and the rangers train for that component of mission all the time. you can plug any group of snatchers in you want dont change the rangers job in the situation. dunno about the offensive being cover wasnt the front line not too far from hospital? sounds like they got a suprise present in form of credible info on pow. once they make call info credible the assault and rescue guys are on call waiting for some kind of mission. make the go call, collect info on the target and area of op, brief, run thru, and go.
