Government austerity measures have the Joint Chiefs of Staff contemplating the unthinkable - combining Delta Force and the SEALs into a single unit: One Killer Force. In this installment of Dalton Fury's Delta Force series, Kolt's career is in jeopardy and worst of all, the final say rests in the hands of men who have reasons to want to see Kolt gone.

Kolt earns his call sign as the action has him racing to the world's hottest combat zones from Syria to Ukraine on hunter-killer missions to eliminate the terrorists before they can enact their deadly mission.

Violently applied force is needed, and needed now before it's too late.
