On one section that I used to work on...it started with over 300 people back in 1990 with a wing commander, 5 squadron leaders and 15 JOs. When I departed 10 years ago there was one squadron leader, two JOs and a 50% mix of service and civvie with a strength of around 100 people. Still had the same number of secondary duties though (which the civvies didn't do). I had 9 secondary duties when I retired.
