"Red Cells" or "Red Teams" is the term used by the US government for units designed to test the effectiveness of its tactics and personnel - the Red Cell is the opposing force in any war game. The term was originally used in the context of the Cold War, a reference to the predominantly red flags of Communist nations (i.e. the USSR and China) with the western nations being the Blue Team. Interestingly, the USSR used the same colors but for the reverse purpose.
These terms and specialized teams are still used today by the US military and intelligence community in the war against terrorism. Often government agencies will set up war games to ensure that their personnel understand the way the enemy think and try and gauge how it will react to any given scenario.
