we find that a large part of the (UK) intelligence community regard intelligence as an end in itself, rather than as a means to an end...

They also seem to risk averse, unwilling to give analysis based likely courses of action and preferring to give straight forward reports on what has or is happening.

We find our best Int staff tend to come from a G3 background and have more of a feel for what the end user requirement is.

It sounds, looking at the previous posts, that your (US military) experiences are not all that different from ours. In terms of military ethos the big differences I have noticed between the US military and the UK military is that the US military appears more self-honest and more goal (success) orientated. I would have thought that both of these when linked would have made your G2 set-up more capable and responsive.
