TACP makes use of USAF ranks and D.Norris should therefor be either Airman or Airman 1st Class, I say give him 1st class.
IIRC the TACP ranks where something like
Airman - TACP candidate
SSgt - TACP graduate
Master Sergeant
Senior Master Sergeant
Chief Master Sergeant
2nd Lieutenant - ALO
1st Lieutenant
