FOB#2 Bomb Burst Patch
The Bomb Burst design first appeared sometime in 1967 and was soon adopted (unofficially) through-out the MAC V SOG Program. The insignia was modified over the years with different ribbons, explosion shapes and skull patterns. One of the earliest bomb burst patches I have ever encountered was from veteran, Joseph Messer who served at Forward Operational Base #2 (FOB#2) in 1967-1968 and had a ribbon that read: FOB#2.
