Viper hit the nail on the head.. All ordnance the hangs from the birds are color coded and the colors are universal no matter if the are a bomb missle tank round and so on.
Yellow ='s live or high explosive.
Brown ='s propellant
Blue ='s inert
Real light or lime green ='s incendiary (i.e white phosphorus)
In the pic provided by Tin Can (great one Thanks for it). The brown stripes point out where the motor is on the winder and the phoenix and the yellow bands show where the HE warhead is on the missles. The gp bombs are live High explosive due to the yellow bands.(Bombs have two designations)
1 yellow band is a slick skin
2 yellow bands is a thermal coated (most common used) the ones shown in the pic.
Sorry got so wordy, hope this helps
