"When U.S. troops withdrew from Afghanistan at the end of 2014, it signaled the end of the longest conflict in the nation's history. Yet we are still at war--no longer with other states, but with a host of new enemies, from nihilistic terrorists and narco-traffickers to transnational criminal cartels, lone wolf assassins, and modern-day pirates. Standing against these foes is a tight-knit fraternity of soldiers, cops, lawyers, and spies. Together, these men have broken down the cultural and institutional boundaries among their respective agencies to engineer a new, network-centric way of fighting: one that uses a seamless web of intelligence analysts, high-tech information networks, and Special Forces units to take the fight to America's enemies as never before. These disciplined, patriotic servicemen form a band of brothers that, over the past half century, has fundamentally reshaped the way America defends itself."--Provided by publisher.
