Mission Statement

Core Mandate

The United States Cyber Command (USCYBERCOM) is a unified combatant command within the U.S. Department of Defense. Its primary function is to unify the direction of cyberspace operations, bolster DoD's cyber capabilities, and integrate cyber expertise to secure the nation's digital domain.

Official Directive

USCYBERCOM's mission, as defined by the DoD, is to plan, coordinate, integrate, synchronize, and conduct activities to direct the operations and defense of specified Department of Defense information networks. It is also tasked to conduct full-spectrum military cyberspace operations to enable actions in all domains, ensure freedom of action in cyberspace for the U.S. and its allies, and deny adversaries the same.

Strategic Focus

The command centralizes command of cyberspace operations, enhances DoD's cyber capabilities, and integrates cyber expertise. This strategic focus aims to defend the information security environment and ensure national security interests are protected in the digital realm.

Organizational Framework

Component Commands

USCYBERCOM comprises several key component commands, each with distinct responsibilities and operational domains:

U.S. Army Cyber Command (ARCYBER)
Marine Corps Forces Cyberspace Command (MARFORCYBER)
U.S. Fleet Cyber Command / U.S. Tenth Fleet (FLTCYBER / 10F)
Sixteenth Air Force (AFCYBER)

Detailed breakdown of component commands:

Command	Acronym	Headquarters
United States Army Cyber Command / Joint Force Headquarters–Cyber	ARCYBER / JFHQ–C	Fort Gordon, Georgia
Marine Corps Forces Cyberspace Command / Joint Force Headquarters–Cyber	MARFORCYBER / JFHQ-C	Fort Meade, Maryland
U.S. Fleet Cyber Command / U.S. Tenth Fleet / Joint Force Headquarters–Cyber	FLTCYBER / 10F / JFHQ–C	Fort Meade, Maryland
Sixteenth Air Force / Air Forces Cyber / Joint Force Headquarters–Cyber	16 AF (AFCYBER) / JFHQ–C	JBSA-Lackland, Texas

Cyber Mission Force (CMF)

The Cyber National Mission Force (CNMF), now a subordinate unified command, is a critical element of USCYBERCOM. It comprises numerous joint cyber teams focused on national defense, combat support, and network protection.

National Mission Teams (NMT)
Combat Mission Teams (CMT)
Cyber Protection Teams (CPT)
National Support Teams (NST)

The CMF's operational roles include:

Defending the nation by identifying and countering adversary cyber activity.
Conducting military cyberspace operations in support of combatant commander priorities.
Protecting DoD networks and critical missions.
Providing analytic and planning support for national and combat missions.

Standing Joint Task Force

The Defense Department Cyber Command (DCDC) operates as a standing joint task force, overseeing critical functions such as the Defense Information Systems Agency (DISA) and Joint Task Force Ares, ensuring integrated cyber defense across the DoD.

Genesis and Evolution

Establishment

USCYBERCOM was established on 21 May 2010, as a sub-unified command under U.S. Strategic Command, headquartered at Fort Meade, Maryland. It was concurrently led by the Director of the National Security Agency (NSA), reflecting a close operational synergy.

Elevation to Unified Command

Initially focused on defensive operations, USCYBERCOM increasingly adopted offensive capabilities. Recognizing its growing importance, it was elevated to the status of a full and independent unified combatant command on 18 August 2017, signifying its enhanced strategic role.

Early Concepts and Challenges

The concept of a dedicated cyber command emerged earlier, with the U.S. Air Force announcing intentions in 2006. Discussions around the need for a distinct cyber warfare branch, and the potential cultural incompatibilities within existing services, highlighted the evolving nature of warfare and the need for specialized expertise.

Leadership

Current Leadership

The command is led by a four-star general or admiral, with specific roles for Deputy Commander, Executive Director, and Senior Enlisted Leader.

Current Commander: LTG William J. Hartman, USA (acting)

A historical overview of USCYBERCOM commanders:

No.	Name	Term	Service Branch
1	Gen. Keith B. Alexander	21 May 2010 – 28 Mar 2014	U.S. Army
-	Lt. Gen. Jon M. Davis (Acting)	29 Mar 2014 – 2 Apr 2014	U.S. Marine Corps
2	Adm. Michael S. Rogers	3 Apr 2014 – 4 May 2018	U.S. Navy
3	Gen. Paul M. Nakasone	4 May 2018 – 2 Feb 2024	U.S. Army
4	Gen. Timothy D. Haugh	2 Feb 2024 – 3 Apr 2025	U.S. Air Force
-	LTG William J. Hartman (Acting)	3 Apr 2025 – Present	U.S. Army

Key Considerations

Civil-Military Integration

Concerns exist regarding the potential for military cyber defense efforts to overshadow civilian initiatives. While USCYBERCOM focuses on DoD networks, its capabilities and potential to assist civilian agencies (like DHS) under specific directives are subjects of ongoing discussion.

Jurisdictional Boundaries

The distinction between defending Department of Defense (DoD) networks (dot-mil) and federal civilian networks (dot-gov) is critical. While USCYBERCOM's primary responsibility lies with DoD assets, executive orders could potentially expand its role in supporting broader federal cyber defense.

Proactive Defense and Privacy

A key strategic approach involves proactive engagement in cyberspace, including offensive operations to counter threats. Balancing these offensive capabilities with the need to protect personal privacy and avoid overreach is a significant challenge for the command.

Operational Scope

Global Hunt Operations

USCYBERCOM conducts "global hunt" operations, identifying adversary activity and vulnerabilities across international networks. These operations, part of a "persistent engagement" strategy, have been conducted in numerous countries, aiming to disrupt threats before they impact U.S. interests.

Offensive Operations

The command possesses a full spectrum of cyber capabilities, including offensive operations. Reports indicate potential U.S. cyber operations targeting foreign infrastructure, such as Russia's electrical grid, underscoring the command's role in deterring and responding to state-sponsored cyber aggression.

Policy Adjustments

Recent policy shifts include a formal pause on offensive cyber operations against specific adversaries, such as Russia, reflecting evolving geopolitical strategies and diplomatic considerations in the cyber domain.
