Due to increasing cyber threats around the world, U.S. Cyber Command officially became a unified combatant command in May. Before then, it fell under U.S. Strategic Command.
The department is now organized under a single commander who reports directly to Defense Secretary James N. Mattis. The change:
Cybercom has been active in the fight against ISIS — Islamic State of Iraq and Syria — terrorists. Its Joint Task Force Ares has provided important support to U.S. Central Command and U.S. Special Operations Command — two other unified cocoms — in the campaign to defeat ISIS on the ground in Iraq and Syria.
The Defense Department is creating a Cyber Mission Force that will include nearly 6,200 personnel in 133 teams that consist of active-duty service members, and those in the National Guard and Reserve.
