Cyber Command – which organizes the military’s cyber resources and synchronizes cyber operations – was established in 2009. It exists as a sub-unified command under US Strategic Command, one of the Department of Defense’s nine Unified Combatant Commands. Hagel will have to evaluate Cyber Command’s maturation to date and determine if it warrants a status elevation to a Unified Combatant Command.
Hagel will also need to decide on Cyber Command’s leadership structure. Currently, General Keith Alexander, command of US Cyber Command, is also serving as the director of the National Security Agency. Hagel must ask if it continues to be necessary and appropriate to have a military command and an intelligence unit under a single line of control.
