Jointery lad,
Methinks think you might have missed something here. Yes, the AAC maybe small but they still have more heicopters than the RAF and the Navy put together. I think you will also find that, unless things have changed in the 2 years since I left, that the main role, (and raison d'etre), of the SH force, and most of the Transport fleet, is to support the Army on ground operations at least until the air superiority version of the Puma enters service.
