First up - Talk Wrench: when 2PUS talks about getting rid of 'agency staff' he isn't talking about defence agencies he's talking about casual labour provided by employment agencies to make up for our undermanning. These bods are v.useful but also v.expensive.
Now the main thread - This is realism guys. We haven't been properly training paras as air delivered light infantry for ages; we've been giving them training jumps so they can wear wings and feel good about themselves. The argument that we need a para capability is tenuous to say the least, but what is very clear is that this is a hugely expensive capability - IIRC it takes 21 C130s (16 in a stream with 5 more making second runs) to deliver the equivalent of a light infantry company which can only sustain itself for 3 days before it has to be relieved or resupplied by those 21 x C130s. I don't think this is remotely cost effective and can understand why it is being put on the shelf for the moment.
I expect even the Paras would prefer more Chinook hours, on time Tristar service and more CAS from Harriers on operations to practising for a company drop that will almost certainly never be needed on operations.
