OK - maybe it isn't you army guys I should be asking, but I've lately got to wondering: I looked at how air power seems to have swung the balance in the Libyan civil war. And I watched this: [LINK]http://www.bbc.co.uk/news/world-europe-14568093[/LINK] and I asked myself - just how do Britain's air defences stand? Without the Americans to help us, how would Typhoons stack up against the T-50 - given that the Russians plan on exporting up to a thousand? AWACS and Typhoon apart, just what air defences does the UK mainland have left? That's a genuine request for information, not a jibe. Did I read that Rapier has been retired?
