The 300th Special Operations Company is the Army's only segregated lycanthrope unit. Forbidden by international accords to engage in combat, the "dog soldiers" lend their skills to the regular Army units, sniffing out IEDs and guarding the troops against things that go bump in the night. Sergeant Decker and his 300th comrade, Sergeant Sobieski, are assigned to a Forward Operating Base deep in the mountains of Afghanistan when they have to face a local threat far more dangerous than roadside bombs or insurgent ambushes.
