True story. Over beer one evening, some friends and I role-played this. - We made a team from the people in the room and people we knew in the local area who could be trusted and would likely join us on short notice. - We excluded the degenerates as they would weigh down the team and get us killed. - We made decisions on who could join based on value vs. risk. E.g. If they were obese, they were excluded unless they had a specialized skill that could not easily be replaced. - We assigned roles and ran scenarios based on our local area. Whiteboards, etc. It actually worked well because we had on our team: - An engineer with a master's degree in sanitation. - Ex military with combat experience - Professional truck driver - Nurse - Mechanic - Guy in logistics - etc.
