America Unplugged (2014)

S1E2 Robert Allen

Upon his return from the Iraq War in 2005, Robert Allen envisioned a project aimed at equipping everyday people with essential survival skills—thus, Sigma 3 was born. Situated on 400 acres in northern Arkansas, this innovative military school empowers individuals to master the art of survival. Participants learn vital techniques ranging from fire-starting and shelter construction to hunting, fishing, and personal security measures.
