I was recently chatting to someone who's (now) just gone back to Afghanistan for an 8 month tour. He said nothing much happens in Iraq now for UK forces and its rare (if ever) that they leave the base other than for "agreed" patrols.
Boring was the word he used and he's no gung-ho idiot - he's done 22 years and has just extended for 2 more to avoid the credit crunch/recession.
Afghanistan, according to him, is a whole different ball-game however and its becoming increasingly clear that we're not going to "win", even if we did have the required equipment/troops (which we don't).
Personally I wonder WTH we're doing there. War on terror? Don't make me laugh, if we were even remotely serious about that we'd be dealing with the real source of Islamic fundamentalism - Pakistan. Pakistan has ALWAYS been the problem, not Iran, Iraq or Afghanistan. They've got nukes though so we have to pretend that's not the case.
