Fascinating subject - loved studying all about this at university.
I think the fundamental problem with the viewpoint of the article is that the MoD hates to push the idea that the British armed forces are being retooled toward fighting as components, and not singly, within multi-national battle groups. The EUs ESDP isn't really succeeding, and so we end up with no ESDP presence in a place like Afghanistan where none of the European forces are really capable, or indeed willing, to fully co-operate a lot of the time. A real shame, because the concept was very exciting.
Worse, each theatre of combat will have different tactical requirements. Will we need all the helicopters in the world for every operation we conduct? Of course not.
It's either we have 10000 tools "just in case", or 10 tools and we start hammering square pegs into round holes. The tax payer wants the former but won't pay for the latter.
