Episode 143 examines what enables guerrilla and insurgent forces to develop military effectiveness on the battlefield.
Our guests discuss why ideological cohesion, social ties, and material resources are insufficient for insurgents to successfully implement guerrilla strategies. Drawing on historical examples and a detailed analysis of the Taliban’s evolution in Afghanistan, they argue that success depends on the professionalization of the force. This includes the recruitment, training, and empowerment of skilled small-unit combat leaders. These leaders enable effective planning, realistic training, adaptation, and task-oriented cohesion. The conversation explores broader implications for understanding insurgencies, counterinsurgency challenges, and security force assistance program
General (Ret.) Stan McChrystal is a retired U.S. Army four-star general, former commander of Joint Special Operations Command and International Security Assistance Force in Afghanistan, founder of the McChrystal Group, and author of multiple books.
Dr. Alec Worsnop is an Assistant Professor at the University of Maryland’s School of Public Policy and a Non-Resident Fellow at the Modern War Institute.

Hahaha our GOFOs were outclassed again. What makes your enemy successful in an IW war. Easy they establish and use parallel hierarchies in the different pillars of the local society to help manipulate the weapons systems of these kinds of war. The weapons systems in these kinds of wars are the different sections of the HN population.
McCrystal read two fictional books on the French approach to IW and did not remember that they lost both times. He should have read Fall, Giap, Mao and some others.
Please google “The Taliban use of Parallel Hierarchies and the Strategic Failure of the U.S.”
Please read “A Century of Conflict “ by Stephen Possony and “The Organizational Weapon” by Philip Selznick”
If you read Mao, don’t read “On Guerrilla Warfare” (a bad set of Cliff Notes by an American where tons gets lost in translation) read Mao’s works on Military Affairs
