Subject: Hybrid Warfare: 

Senior military officials recently testified[Footnote 1] before 
Congress that current and future adversaries are likely to use "hybrid 
warfare" tactics, a blending of conventional and irregular approaches 
across the full spectrum of conflict. In addition, several academic 
and professional trade publications have commented that future 
conflict will likely be characterized by a fusion of different forms 
of warfare rather than a singular approach. The overarching 
implication of hybrid warfare is that U.S. forces must become more 
adaptable and flexible in order to defeat adversaries that employ an 
array of lethal technologies to protracted, population-centric 
conflicts such as those in Iraq and Afghanistan. Department of Defense 
(DOD) officials have discussed the need to counter the continuum of 
threats that U.S. forces could face from non-state-and state-sponsored 
adversaries, including computer network and satellite attacks; 
portable surface-to-air missiles; improvised explosive devices; 
information and media manipulation; and chemical, biological, 
radiological, nuclear, and high-yield explosive devices. 

In light of references to "hybrid warfare" by senior military 
officials and possible implications it could have for DOD's strategic 
planning, you requested we examine: (1) whether DOD has defined hybrid 
warfare and how hybrid warfare differs from other types of warfare and 
(2) the extent to which DOD is considering the implications of hybrid 
warfare in its overarching strategic planning documents. On June 16, 
2010, we met with your staff to discuss the preliminary results of our 
work. This report formally transmits our final response to your 
request. 

Scope and Methodology: 

To determine how DOD defines hybrid warfare, how hybrid warfare 
differs from other types of warfare, and how DOD uses the concept in 
its strategic planning documents, we reviewed and analyzed DOD 
doctrine, guidance, policy, and strategic planning documents, and 
interviewed Office of the Secretary of Defense (OSD), Joint Staff, 
service headquarters, Defense Intelligence Agency, and combatant 
command officials. More specifically, our review and analysis included 
the most recent National Defense Strategy; the 2010 Quadrennial 
Defense Review Report; and the 2010 Joint Operating Environment. 

We conducted this performance audit from January 2010 to September 
2010 in accordance with generally accepted government auditing 
standards. These standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives. 

Summary: 

Senior military officials in recent public testimony asserted the 
increased likelihood of U.S. forces encountering an adversary that 
uses hybrid warfare tactics, techniques, and procedures. However, DOD 
has not officially defined hybrid warfare at this time and has no 
plans to do so because DOD does not consider it a new form of warfare. 
Rather, officials from OSD, the Joint Staff, the four military 
services, and U.S. Joint Forces Command told us that their use of the 
term hybrid warfare describes the increasing complexity of future 
conflicts as well as the nature of the threat. Moreover, the DOD 
organizations we met with differed on their descriptions of hybrid 
warfare. For example, according to Air Force officials, hybrid warfare 
is a potent, complex variation of irregular warfare. U.S. Special 
Operations Command officials, though, do not use the term hybrid 
warfare, stating that current doctrine on traditional and irregular 
warfare is sufficient to describe the current and future operational 
environment. 

Although hybrid warfare is not an official term, we found references 
to "hybrid" and hybrid-related concepts in some DOD strategic planning 
documents; however, "hybrid warfare" has not been incorporated into 
DOD doctrine. For example, according to OSD officials, hybrid was used 
in the 2010 Quadrennial Defense Review Report to draw attention to the 
increasing complexity of future conflicts and the need for adaptable, 
resilient U.S. forces, and not to introduce a new form of warfare. The 
military services and U.S. Joint Forces Command also use the term 
"hybrid" in some of their strategic planning documents to articulate 
how each is addressing current and future threats, such as the cyber 
threat; however, the term full spectrum often is used in addition to 
or in lieu of hybrid.

Hybrid Warfare: 

Briefing to the Subcommittee on Terrorism, Unconventional Threats and 
Capabilities, Committee on Armed Services, House of Representatives: 

September 10, 2010: 

Overview: 
* Introduction; 
* Key Questions; 
* Scope and Methodology; 
* Summary; 
* Background; 
* Observations; 
* Agency Comments; 
* Enclosure I: DOD Definitions of Warfare; 
* Enclosure II: Comments from the Department of Defense. 

Introduction: 

Senior military officials used the term "hybrid warfare" during 
testimony before Congress between 2008-2010 to describe the methods 
used by U.S. adversaries in Iraq and Afghanistan, and what U.S. forces 
are likely to encounter in future conflicts. 

Moreover, many academic and professional trade publications have 
commented that future conflict will likely be characterized by a 
fusion of different forms of warfare rather than a singular approach. 

Hybrid warfare tactics consist of the blending of conventional, 
unconventional, and irregular approaches to warfare across the full 
spectrum of conflict. 

Key Questions: 

In response to your request, our objectives in this review were to 
determine: 

1. Whether DOD has defined hybrid warfare and how hybrid warfare 
differs from other types of warfare. 

2. The extent to which DOD is considering the implications of hybrid 
warfare in its overarching strategic planning documents. 

We conducted this review from January 2010 to September 2010 in 
accordance with generally accepted government auditing standards. 

Scope and Methodology: 

To determine whether DOD has defined or intends to define hybrid 
warfare and how hybrid warfare is different from other types of 
warfare, we examined DOD-approved definitions of warfare-—such as 
irregular and unconventional warfare-—and compared them with the 
concept of hybrid warfare. We also met with Office of the Secretary of
Defense (OSD), Joint Staff, service headquarters, Defense Intelligence 
Agency, and combatant command officials to obtain their perspectives 
on the term and determine whether they have formally defined it (see 
pages 6-7). 

To determine the extent to which DOD is considering the implications 
of hybrid warfare in its overarching strategic planning documents, we 
reviewed and analyzed DOD strategies, doctrine, guidance, and 
policies, including the 2008 National Defense Strategy,[Footnote 2] 
the 2010 Quadrennial Defense Review Report,[Footnote 3] the 2010 Joint 
Operating Environment,[Footnote 4] and the 2009 Capstone Concept for 
Joint Operations.[Footnote 5] We also discussed this matter with DOD 
officials from the organizations listed on pages 6-7. 

We met with officials from the following DOD organizations: 

* The Joint Staff, Joint Force Development and Integration Division. 

* Office of the Assistant Secretary of Defense, Special Operations/Low 
Intensity Conflict & Interdependent Capabilities, Office of Special 
Operations & Combating Terrorism. 

* Office of the Under Secretary of Defense for Policy, Force 
Development. 

* Office of the Under Secretary of Defense, Comptroller. 

* Office of the Secretary of Defense, Cost Assessment and Program 
Evaluation. 

* Defense Intelligence Agency. 

* U.S. Joint Forces Command: 
- Joint Irregular Warfare Center; 
- Joint Futures Group; 
- Joint Center for Operational Analysis; 
- Joint Training and Joint Warfighting Center Directorate; 
- Joint Concept Development and Experimentation Directorate. 

* U.S. Special Operations Command: 
- Operational Plans and Joint Force Development Directorate; 
- Joint Capability Development Directorate; 
- Joint Concept Development and Experimentation Directorate; 
- Strategic Plans and Policy Directorate. 

* U.S. Army Headquarters: 
- Office of the Deputy Chief of Staff for Operations and Plans; 
- Office of the Deputy Chief of Staff for Intelligence. 

* U.S. Army Training and Doctrine Command. 

* U.S. Air Force Headquarters: 
- Irregular Warfare Requirements Directorate. 

* U.S. Navy Headquarters: 
- Navy Irregular Warfare Office. 

* U.S. Marine Corps Headquarters: 
- Marine Corps Combat Development Command, Concepts and Plans. 

Summary: 

DOD has not officially defined "hybrid warfare" at this time and has 
no plans to do so because DOD does not consider it a new form of 
warfare. 

DOD officials from the majority of organizations we visited agreed 
that "hybrid warfare" encompasses all elements of warfare across the 
spectrum. Therefore, to define hybrid warfare risks omitting key and 
unforeseen elements. 

DOD officials use the term "hybrid" to describe the increasing 
complexity of conflict that will require a highly adaptable and 
resilient response from U.S. forces, and not to articulate a new form 
of warfare. 

The term "hybrid" and hybrid-related concepts appear in DOD 
overarching strategic planning documents (e.g., 2010 Quadrennial 
Defense Review Report); however, "hybrid warfare" has not been 
incorporated into DOD doctrine. 

Background: 

Department of Defense Dictionary of Military and Associated Terms 
(Joint Publication 1-02), sets forth standard U.S. military and 
associated terminology that, together with their definitions, 
constitutes approved DOD terminology. There are approximately
6,000 terms in Joint Publication 1-02. 

Chairman of the Joint Chiefs of Staff Instruction 5705.01 C, 
Standardization of Military and Associated Terminology, stipulates 
four methods to add, modify, or delete DOD terminology in Joint 
Publication 1-02. 

As shown in figure 1, according to Joint Staff officials, the approval 
process to incorporate a new term in Joint Publication 1-02 can take 
place immediately to approximately 18 months. The majority of approved 
terms are proposed due to their inclusion in existing joint doctrine 
publications. 

Figure 1: Methods to Incorporate New DOD Terminology into Joint 
Publication 1-02: 

[Refer to PDF for image: illustration] 

Illustration sizing approximated based on agency descriptions. 

Directed by Secretary of Defense, Deputy Secretary of Defense, or the 
Chairman of the Joint Chiefs of Staff: Immediate. 

Proposed from DOD directives and instructions or Chairman of the Joint 
Chiefs of Staff instructions[A]: 9 months. 

Proposed from joint doctrine publications[A]: 18 months. 

Source: GAO analysis of DOD's terminology approval process. 

[A] The fourth method to incorporate a new term into Joint Publication 
1-02 is through terminology proposed from the NATO Glossary of Terms 
and Definitions (English and French), which may be proposed for 
adoption and inclusion by the Department of Defense in the appropriate 
Joint Publication, Chairman of the Joint Chiefs of Staff Instruction, 
or DOD document. 

[End of figure] 

Observations: Objective 1: Definition: 

DOD has not formally defined hybrid warfare at this time and does not 
plan to do so because DOD does not consider it a new form of warfare. 

DOD officials indicated that the term "hybrid" is more relevant to 
describe the increasing complexity of conflict that will require a 
highly adaptable and resilient response from U.S. forces rather than a 
new form of warfare. 

DOD officials have different characterizations of recent conflicts. 
For example: 

* Air Force officials stated that the conflicts in Iraq and 
Afghanistan are irregular warfare and hybrid, while Army and Navy 
officials both considered Afghanistan irregular warfare and Iraq 
initially conventional warfare and then later, irregular warfare. 

* U.S. Special Operations Command and Army officials characterized the 
Russia-Georgia conflict as conventional warfare, while Air Force 
officials considered it a hybrid conflict. 

Discussions about hybrid threats, as opposed to hybrid warfare, are 
ongoing within DOD; however, most of the DOD officials whom we spoke 
with stated that it was premature to incorporate hybrid threats into 
doctrine. 

The North Atlantic Treaty Organization (NATO) has defined hybrid 
threat as follows, and is developing doctrine on countering the hybrid 
threat. 

* "A hybrid threat is one posed by any current or potential adversary, 
including state, non-state and terrorists, with the ability, whether 
demonstrated or likely, to simultaneously employ conventional and non 
conventional means adaptively, in pursuit of their objectives." 
[Footnote 6] 

Observations: Objective 1: The Hybrid Warfare Concept: 

According to our analysis of DOD and academic documents, hybrid 
warfare blends conventional[Footnote 7] and irregular warfare[Footnote 
8] approaches across the full spectrum of conflict. Figure 2 displays 
a sample of approaches that could be included in hybrid warfare.

and academic writings. 

[End of figure] 

Observations: Objective 1: Definition Comparison: 

DOD officials have differing views on whether or how hybrid warfare 
differs from other types of warfare.[Footnote 9] 

* According to Air Force officials, hybrid warfare is more potent and 
complex than irregular warfare due to increased tempo, complexity, 
diversity, and wider orchestration across national borders, which are 
all exacerbated by the ease with which adversaries can communicate, 
access international resources and funding, and acquire more lethal 
and sophisticated weaponry. 

* Special Operations Command officials stated that hybrid warfare is 
no different from current doctrinal forms of warfare employed across 
the spectrum of conflict. 

* Navy officials stated that hybrid is synonymous with full spectrum and
encompasses both conventional warfare and unconventional warfare. 

* Marine Corps officials use the term "hybrid" to describe the 
potential threat posed by both state and non-state actors and believe 
that hybrid warfare is not a new form of warfare; rather it is 
synonymous with full spectrum conflict and is already adequately 
covered in current doctrine. 

Observations: Objective 1: Unofficial Definitions: 

The following are examples of unofficial definitions of hybrid 
warfare/threat that we found in military concept and briefing 
documents and in academic writings (emphases added): 

Hybrid Warfare: Conflict executed by either state and/or non-state 
threats that employs multiple modes of warfare to include conventional 
capabilities, irregular tactics, and criminal disorder. (U.S. Joint 
Forces Command, Joint Center for Operational Analysis briefing on 
"Joint Adaptation to Hybrid War") 

Hybrid Threat: An adversary that simultaneously and adaptively employs 
some fused combination of (1) political, military, economic, social 
and information means and (2) conventional, irregular, terrorism and 
disruptive/criminal conflict methods. It may include a combination of 
state and non-state actors. (Working definition derived by U.S. Joint 
Forces Command, Joint Irregular Warfare Center, 2008-2009) 

Hybrid Threat: A threat that simultaneously employs regular and 
irregular forces, including terrorist and criminal elements to achieve 
their objectives using an ever-changing variety of conventional and 
unconventional tactics to create multiple dilemmas. (U.S. Army 
Training and Doctrine Command's Operational Environment, 2009-2025) 

Hybrid Threats: 
Threats that incorporate a full range of different modes of warfare 
including conventional capabilities, irregular tactics and formations, 
terrorist acts including indiscriminate violence and coercion, and 
criminal disorder, conducted by both states and a variety of non-state 
actors.[Footnote 10] 

Observations: Objective 2: Strategic Planning: 

DOD uses the term "hybrid" in select strategic planning documents to 
articulate how it is addressing current and future threats. For 
example: 

* The term "hybrid" is mentioned twice in the 2010 Quadrennial Defense 
Review Report to describe the approaches and capabilities that 
potential adversaries may use against U.S. forces and counteractions 
DOD can take. 

* The term "hybrid" is used in the 2010 Joint Operating Environment to 
describe the combination of lethal technology and the protracted, 
population-centric nature of contemporary and future conflicts. 

* The 2009 Capstone Concept for Joint Operations states that future 
conflicts will appear as hybrids comprising diverse, dynamic, and 
simultaneous combinations of organizations, technologies, and 
techniques that defy categorization. 

* The 2010 Army Modernization Strategy[Footnote 11] states that the 
Army must continue to upgrade its capabilities to remain a dominant 
force and successful against hybrid threats, global terrorists, and 
followers of extremist ideologies. 

Some DOD organizations have adopted the term "full spectrum 
operations" in addition to or in lieu of the term "hybrid." 

* The 2010 Army Posture Statement[Footnote 12] uses the term "full 
spectrum operations"[Footnote 13] in addition to hybrid threats to 
describe current and future military operations. 

* According to Army officials, full spectrum operations underpin both 
conventional and irregular warfare. 

* The Air Force Global Partnership Strategy[Footnote 14] states that 
as the United States fights insurgencies and terrorism, the U.S. Air 
Force must maintain its capacity to conduct full spectrum operations 
to defeat U.S. enemies in operations of traditional and irregular 
character.

Enclosure I: DOD Definitions of Warfare: 

Department of Defense Dictionary of Military and Associated Terms 
(Joint Publication 1-02), includes the following definitions of 
warfare:[Footnote 15] 

Acoustic Warfare (DOD, NATO): Action involving the use of underwater 
acoustic energy to determine, exploit, reduce, or prevent hostile use 
of the underwater acoustic spectrum and actions which retain friendly 
use of the underwater acoustic spectrum. 

Antisubmarine Warfare (DOD, NATO): Operations conducted with the 
intention of denying the enemy the effective use of submarines.
Atomic Warfare (DOD, NATO) See nuclear warfare. 

Biological Warfare (DOD, NATO): Employment of biological agents to 
produce casualties in personnel or animals, or damage to plants or 
materiel; or defense against such employment. 

Chemical Warfare (DOD): All aspects of military operations involving 
the employment of lethal and incapacitating munitions/agents and the 
warning and protective measures associated with such offensive 
operations. Since riot control agents and herbicides are not 
considered to be chemical warfare agents, those two items will be 
referred to separately or under the broader term "chemical," which 
will be used to include all types of chemical munitions/agents 
collectively. 

Directed-Energy Warfare (DOD): Military action involving the use of 
directed-energy weapons, devices, and countermeasures to either cause 
direct damage or destruction of enemy equipment, facilities, and 
personnel, or to determine, exploit, reduce, or prevent hostile use of 
the electromagnetic spectrum through damage, destruction, and 
disruption. It also includes actions taken to protect friendly 
equipment, facilities, and personnel and retain friendly use of the 
electromagnetic spectrum. 

Electronic Warfare (DOD): Military action involving the use of 
electromagnetic and directed energy to control the electromagnetic 
spectrum or to attack the enemy. Electronic warfare consists of three 
divisions: electronic attack, electronic protection, and electronic 
warfare support. 

Guerrilla Warfare (DOD, NATO): Military and paramilitary operations 
conducted in enemy-held or hostile territory by irregular, 
predominantly indigenous forces. 

Irregular Warfare (DOD): A violent struggle among state and non-state 
actors for legitimacy and influence over the relevant population(s). 
Irregular warfare favors indirect and asymmetric approaches, though it 
may employ the full range of military and other capacities, in order 
to erode an adversary's power, influence, and will. 

Land Mine Warfare (DOD, NATO): See mine warfare. 

Mine Warfare (DOD): The strategic, operational, and tactical use of 
mines and mine countermeasures. Mine warfare is divided into two basic 
subdivisions: the laying of mines to degrade the enemy's capabilities 
to wage land, air, and maritime warfare; and the countering of enemy-
laid mines to permit friendly maneuver or use of selected land or sea 
areas. 

Multinational Warfare (DOD): Warfare conducted by forces of two or 
more nations, usually undertaken within the structure of a coalition 
or alliance. 

Naval Coastal Warfare (DOD): Coastal sea control, harbor defense, and 
port security, executed both in coastal areas outside the United 
States in support of national policy and in the United States as part 
of this Nation's defense. 

Naval Expeditionary Warfare (DOD): Military operations mounted from 
the sea, usually on short notice, consisting of forward deployed, or 
rapidly deployable, self-sustaining naval forces tailored to achieve a 
clearly stated objective. 

Naval Special Warfare (DOD): A designated naval warfare specialty that 
conducts operations in the coastal, riverine, and maritime 
environments. Naval special warfare emphasizes small, flexible, mobile 
units operating under, on, and from the sea. These operations are 
characterized by stealth, speed, and precise, violent application of 
force. 

Nuclear Warfare (DOD, NATO): Warfare involving the employment of 
nuclear weapons. Partisan Warfare (DOD, NATO) Not to be used. See 
guerrilla warfare. 

Surface Warfare (DOD): That portion of maritime warfare in which 
operations are conducted to destroy or neutralize enemy naval surface 
forces and merchant vessels. 

Unconventional Warfare (DOD): A broad spectrum of military and 
paramilitary operations, normally of long duration, predominantly 
conducted through, with, or by indigenous or surrogate forces who are 
organized, trained, equipped, supported, and directed in varying 
degrees by an external source. It includes, but is not limited to, 
guerrilla warfare, subversion, sabotage, intelligence activities, and 
unconventional assisted recovery. 

Under Sea Warfare (DOD): Operations conducted to establish and 
maintain control of the underwater environment by denying an opposing 
force the effective use of underwater systems and weapons. It includes 
offensive and defensive submarine, antisubmarine, and mine warfare 
operations.
