Patrick Paterson’s monograph, Training Surrogate Forces in International Humanitarian Law: Lessons from Peru, Colombia, El Salvador, and Iraq, leverages the author’s vast experience in Latin American history to examine how U.S. Special Operations Forces (USSOF) train surrogate forces. He argues that it is necessary to employ United States Special Operations Command’s (USSOCOM) indirect approach to grow and build partnership capacity through foreign internal defense (FID) and to find a balance with international humanitarian law (IHL). Paterson also examines the legal issues and restrictions on training and equipping foreign forces and the impact of these exchanges with our partners. His research methodology includes extensive interviews and incorporates a historical case study approach, examining FID efforts in Peru, Colombia, and El Salvador for lessons learned, and then compares and contrasts USSOF train and equip efforts in Iraq.
