The services of private security companies have expanded so much over the last 20 years that they are now referred to as private military companies (PMCs) in some circles. PMCs have assumed all the different roles of war, from backend logistics, to training, to consulting, to battlefield operations, and more. The private military industry was a $218 billion industry in 2014 and business is growing, according to the Vice video below.

This VICE video explores the origins of the PMC industry and how the war on terror has fueled its growth.
