“As the interwar period suggests, wargaming is one of the most effective means available to offer senior leaders a glimpse of future conflict, however incomplete. Wargames offer opportunities to test new ideas and explore the art of the possible. They help us imagine alternative ways of operating and envision new capabilities that might make a difference on future battlefields.”1

– Deputy Secretary of Defense Robert O. Work and General Paul Selva, Vice Chairman of the Joint Chiefs of Staff, December 8, 2015

Red “cells” and red “teams” are frequently confused for each other. A red cell is an entity typically led by a staff intelligence officer tasked with representing enemy doctrine and its likely courses of action. A red team is tasked with challenging perceived norms and assumptions made by a commander and his staff in order to improve the validity and quality of a plan.
