New Zealands system worked very well. You had the choice to join the Territorials and received a commission based on your job grading or previous military experience (this was appropriate to the RAAF controllers that came over as they were all Flt Looeys).
This gave the RNZAF deployable Controllers in peace time and war if required. Additionally the controllers participated in MAOT courses etc. You could also go flying and participate in all activities synonymous with Air Force life.....ie. Bar-O-Clock
Best 2 years of my life....
Yippe Ki Yi Yay!
