Shadow Command is a group of elite operatives from multiple countries, with the goal of infiltration and destruction of the Russian war machine from inside. It is a branch of the Allied Intellegence Services.
Shadow Command was founded in 1924, and shortly after Mortar and Goggles applied and were accepted. Red came under the attention of the Allied Intellegence Services and was recruited by Shadow Command.
Shadow Command has 3 known field operatives: Red, Goggles, and Mortar. Shadow Command also has multiple informants, such as the Priest in the Assassin mission - but it is more likely that they are informants for the Allied Intellegence Services and not directly to Shadow Command.
