HOGs in the shadows: combat stories from Marine snipers in Iraq by Milo S. Afong. I'm partway into it, and it is well-written. It's a collection of reports from different snipers and teams.
I also picked up one by a British sniper, but I forgot the title-- Prince of Wales' Regiment, I remember that much.
I'm not a sniper-fanatic, but they do make for good reading pretty often, and as very small teams, they make for good RPG fodder. I can't remember the last time I tied a PC group in knots with a sniper.....
