The USAF usually takes a ribbing from the other services about what we do in their minds, but this is an example of what we do to bring an F-15 fighter jet to full weapons capability to our phenomenal pilots can do their job in bringing in the firepower to our troops on the ground in harm's way... It is what we do to keep those birds equipped... Whether it be a Training aircraft or a huge C-130 and everything in between... And we refuel these birds in the air with big KC-135 Tankers to keep these birds going!!! GO AIR FORCE!!!
