Know Your Enemy. Liam Scott is back in Afghanistan, this time with
4 Rifles. No longer the new guy, it's his chance to prove himself
and take the lead. But the warzone has changed dramatically, and so

and his new patrol face daily attacks from Taliban insurgents. But
the real threat seems to be coming from within his unit. It looks
like there's a traitor in their midst.
