Armored cars, burner phones, top-notch weaponry and top-secret missions -- this is the life of today's private military contractor. Like author Simon Chase, many PMCs were once the world's top military operatives, and since retiring from outfits like US Navy SEAL TEAM Six and the UK's Special Boat Service, they have devoted their lives to executing sensitive and hazardous missions overseas.

Working at the request of U.S. and British government entities as well as for private clients, he takes on jobs that require zero footprint, with no trace of their actions left behind. Chase delivers firsthand accounts of tracking Bin Laden in Afghanistan and being one of the first responders after the attack on the U.S. Consulate in Benghazi. We see his teams defuse terrorist bombs, guard dignitaries, and protect convoys traveling through perilous territory -- and then there are the really big jobs: top-secret zero footprint missions that include searching for High Value Targets and setting up arms shipping networks.

The missions in Zero Footprint will shock readers, but so will the personal dangers. Chase and the men he works with operate without government backup or air rescue. If they die serving their country, they remain anonymous. There are no military honors or benefits. Contractors like Simon Chase are the unsung heroes in the war against terrorism, a strong, but largely invisible force -- until now.
