The "Rebel Ramp" is where Detachment 1, 834th Air Division (7th Air Force) parked their C-130 Hercules transports at Tan Son Nhut AB, RVN throughout much of the Vietnam War.  The 834th AD was deactivated on 1 December 1971 and their flight line unit was then redesignated Det. 1, 374th Tactical Airlift Wing (flying out of CCK AB, Taiwan).
 
Scroll down towards the bottom of this photo and you will see a transient aircraft, marked in pen as: C-141
 
Below the C-141 you can see the C-130s in their open revetments.  This is the "Rebel Ramp" on Tan Son Nhut, also known as the Airlift Control Center (ALCC) ramp.

The commercial Tan Son Nhut International Airport pax terminal, where many troops arrived/departed from Vietnam is just out of sight on the middle/left side of this photo (left of the original TSN Control Tower and POL tank farm) where the B-707 with the PanAm logo is visible on it's tail.
 
I was stationed at Tan Son Nhut from Sept 1971 - 1972.  I was a crew chief & flight mechanic on "Scatback" T-39 Sabreliners.  Our open revetments and seven of our assigned aircraft are visible in the middle of this photo, marked: T-39
 
Our Scatback pilots worked out of Bldg 602 (the large white building that the T-39s are pointed at) which also served as TSN Base Operations.
 
Although we were an Air Force airlift squadron, we flew many of your U.S. Army general officers around Vietnam and SEA during the war, including Generals Westmoreland, Abrams and Weyand.
