Anyway, I started out as a 40230A Photo Optics and Electronic Sensor Tech
which delt with all the Photo Stuff on the RF-4C ,SR-71,RB57,
then transitioned to 30155A ( kinda same thing BUT added more Neat
Sensor stuff to the list..) then to 32950A- Electronic Sensors FTD
Instructor on AC119K and AC130E/H Gunships at Field #9.
I Taught Field Maint/OJT to almost every tech from 1971 thru 1973 at #9
with the 415th SOTS (Became the 834 AMS)Long after it moved from Ohio to
Eglin Aux AFB #9 (Hurlburt field) Fl.
the Equipment included AAD4,and NOD on the AC119 and AAD6,7 (IR Sensor),
AVQ 18,19 (LTD,LTD/R),LLLTV, GLINT,Video Tape,Video Distribution,and
associated EQ on the AC130's...I was also involved in the transition field mod
to the LLLTV to become the GLINT...

has 1,3,5,7 levels. Special Electronics"...99125 only had a "2" level.
