With the evolving character of the modern warfare - induction of new systems every day - and requirement to quickly adapt -- I do not think that IAF or PAF are overstaffed - Infact, they are slightly understaffed considering the average skill level of non-commissioned personnel compared to airforces like USAF where, for example, the NCOs can handle the flight line operations on their own without an officer standing on their heads 24/7.
The Army would give you hell in physical domains but the airforce would F** your brain up.
