Frank Sobchak, a retired Special Forces colonel and author of "Training for Victory: U.S. Special Forces Advisory Operations from El Salvador to Afghanistan," joins podcast editor Ron Granieri to discuss the complexities of security force assistance (SFA). Their conversation delves into the challenges of measuring success in advisory missions and avoiding deeper U.S. combat commitments. Frank's research, based on five case studies (El Salvador, the Philippines, Colombia, Iraq, and Afghanistan), identifies key variables influencing SFA success. He cites advisor language and cultural awareness, advisor-to-host nation ratio, consistency in advisor pairing, combat advising, and the ability to organize host nation units. He emphasized that while not all factors need to be perfectly aligned, a majority must be in place for a mission to succeed.
