Oh, and while I'm on about Recon, I sat on top of the building site (as mentioned above), directly opposite base (A) on the snow map. 3 enemies went up onto that roof - 1 sniper, 1 assault and 1 medic. It was obvious the medic was there to ressurect either of the others should they be shot. So instead of taking out the assault and sniper, I took my time and singled out the medic, as once he's gone, the other two were f*cked. Took about 20 seconds (which seems ages in game time trying to pick someone out for a headshot when they're constantly moving around on a roof), but eventually the medic was directly between both the other two guys. BANG. Headshot. Awesome. The other guys stopped for a second, looked around frantically as I ducked away behind some wooden planks on the building site. I slowly moved to the corner, took aim, and BANG! Sniper taken out. The assault guy was left on his own and was easy pickings. Why he didn't just run away I don't know.
Great sense of satisfaction, though. You also get that when you hit a target so, so far away with a headshot as he's running. So you aim ahead of his projected run and fire in the hope he'll run into the bullet. It's great.
