Procured Numbers Instead of InService Numbers?
The InService Numbers of Aircraft are merely estimated and doesn't give the whole picture, changes from time to time depending on aircraft reserves, attrition figures etc.
@Mayank Prasoon: I would prefer this one. It is directly from the Minister of State for Defence in Lok Sabha in July 2019. At the link given, there are three tables: one for number of officers, one for airmen, and third for personnel from north east. I think for air force, the sum of 'held strength' of both first table (12142) and second table (129094) can be used for total personnel strength of IAF (total = 141236). —Sarvatra (talk, contribs) 20:34, 15 October 2019 (UTC)
