I was a 3C052 (Communications Computer Systems Programmer/Analyst) with a TS/SCI/Poly clearance.
I supported SCIFs (Secure Compartmentalized Information Facilities) and Secure Datacenters that managed the air traffic, traffic control, and routing of F-16, A-10 Warthogs, and Boeing AH-64 Apache Gunships.
I joked that if I were ever attacked, I could swing a mean mouse and I was certified on the 9mm sidearm and M16A1 assault rifle.
