I was a NSF sergeant Command School Instructor in SISPEC (now known as SCS).
After ORD, I received a NS letter to inform me that my reservist NS unit is ISTAR.
ISTAR stands for Intelligence, Surveillance, Target Acquisition, and Reconnaissance.
What is it?
Got Wear jungle Hat and walk 72km or not ?
