America Unplugged - Season 1 Episode 2 Robert Allen
6.00 21 minutes After returning home from the second Iraq war in 2005, Robert Allen created his vision of bringing a military school to the masses – Sigma 3. Based on 400 acres in northern Arkansas, Sigma 3 teaches ordinary citizens how to truly survive with nothing – from making fire, to building a shelter to hunting, fishing and self-defense/security detail.
