Taken in the motor Pool at McCully Barracks.
To decipher the unit as best as I can remember:
7A Seventh Army George Patton comanding in WWII.
3 Third Battalion. This unit goes back to the Revolutionary war and was the third artilery unit formed.
F21 I am going with 21st Field artilery
FB34 stands for Firing Battery Vehicle 34.
The Honest John missle though never was used in anger for which I thank God, it was very impressive when fired. It broke the speed of sound by the time it left the launcher. It was extremely loud as a solid fuel rocket tends to be.
At night it lit up the entire county side. We had High explosive rounds and Nukes so I was told.
