I thought the back end was Air Force types?
From the TACAMO web site.
"Aircrews normally consist of 14 to 16 members including three pilots, two naval flight officers and 10 Sailors..."
For some missions a joint (all services) Battle Staff is added to the basic crew which includes the crew above, an Information Systems Officer and team, an Airborne Emergency Action Officer (an Admiral or General officer), an Intelligence Officer, Meteorologist, and an Airborne Battle Operations Team.
