I am constantly looking around the map, checking the sight lines, and looking for other snipers/threats. I generally stay unzoomed unless I need to sight in on a target, as wide and far is better than narrow and focused for spotting enemy targets. In games that allow spotting, I'm constantly doing that, and running motion sensors/MAVs depending on what I have on me to get an idea where the bad guys are. Otherwise I am calling out threats, enemy movements, and keeping my team mates up to date what's going on via voice chat.
When I do finally take the shot, I do it as quick and Zen like as I can, as the longer you hold your breath the more likely you are to mess the shot up. The target is also more likely to see the scope glint, and shoot back the longer you wait too. Headshots are nice, but sometimes you have to center mass snap shot as quickly as you can if the target is moving, or you will lose the shot. Once I've whacked a few targets, and the bad guys know where I'm at, its time to move and setup another sight line.
TL;DR: I am doing my job.
Edit: On clarity, apparently map awareness and spotting's this rare thing for most recon players out there, so that qualifies as "odd". Sad but true. For more weird sniper stuff, I come up with snappy Australian style sniper insults every time I whack another sniper.
