Hybrid warfare was defined by Frank Hoffman in 2007 as the emerging simultaneous use of multiple types of warfare by flexible and sophisticated adversaries who understand that successful conflict requires a variety of forms designed to fit the goals at the time. While there is no clear, accepted definition, methods include political warfare and blend conventional warfare, irregular warfare, and cyberwarfare with other influencing methods, such as fake news, diplomacy, lawfare, regime change, and foreign electoral intervention. By combining kinetic operations with subversive efforts, the aggressor intends to avoid attribution or retribution. The concept of hybrid warfare has been criticized by a number of academics and practitioners, who say that it is vague and has disputed constitutive elements and historical distortions.
Definition
There is no universally accepted definition of hybrid warfare, with a debate over its utility and whether it simply refers to irregular methods to counter a conventionally superior force. The vagueness of the term means that it is often used as a catch-all term for all non-linear threats. Hybrid warfare is warfare which includes some, parts, or all of the following aspects:
A non-standard, complex, and fluid adversary. A hybrid adversary can be state or non-state. For example, in the Israel–Hezbollah War of 2006 and the Syrian Civil War, the main adversaries were non-state entities within the state system. The non-state actors can act as proxies for countries but have independent agendas as well. On the other hand, Russian involvement in Ukraine (pre-2022) can be described as a traditional state actor waging a hybrid war (in addition to using a local hybrid proxy) although Russia denied involvement in the 2014 Ukraine conflict. Use of combination of conventional and irregular methods. Methods and tactics may include conventional capabilities, irregular tactics, irregular formations, diplomacy, politics, terrorist acts, indiscriminate violence, and criminal activity. A hybrid adversary may also use clandestine actions to avoid attribution or retribution. The methods are used simultaneously across the spectrum of conflict with a unified strategy. A current example is the Islamic State's transnational aspirations, blended tactics, structured formations, and cruel use of terrorism as part of its arsenal. Use of advanced weapons systems and other disruptive technologies. Such weapons can be now bought at bargain prices. Use of mass communication for propaganda. The growth of mass communication networks offers powerful propaganda and recruiting tools. The use of fake-news websites to spread false stories is a possible element of hybrid warfare. Three distinct battlefields. They are the conventional battlefield, the indigenous population of the conflict zone, and the international community.
Other definitions The Chief of Staff of the US Army defined a hybrid threat as an adversary that incorporates "diverse and dynamic combinations of conventional, irregular, terrorist and criminal capabilities." The US Joint Forces Command defines a hybrid threat as "any adversary that simultaneously and adaptively employs a tailored mix of conventional, irregular, terrorism and criminal means or activities in the operational battle space. Rather than a single entity, a hybrid threat or challenger may be a combination of state and nonstate actors." The US Army defined a hybrid threat in 2011 as "the diverse and dynamic combination of regular forces, irregular forces, criminal elements, or a combination of these forces and elements all unified to achieve mutually benefiting effects." NATO uses the term to describe "adversaries with the ability to simultaneously employ conventional and non-conventional means adaptively in pursuit of their objectives." According to the 2017-inaugurated European Centre of Excellence for Countering Hybrid Threats, "hybrid threats are methods and activities that are targeted towards vulnerabilities of the opponent" where the "range of methods and activities is wide".
Relation to the grey-zone
The concept of grey-zone conflicts or warfare is distinct from the concept of hybrid warfare, although the two are intimately linked, as in the modern era states most often apply unconventional tools and hybrid techniques in the grey-zone. However many of the unconventional tools used by states in the grey-zone such as propaganda campaigns, economic pressure, and the use of non-state entities do not cross over the threshold into formalized state-level aggression.
Effectiveness
Traditional militaries find it hard to respond to hybrid warfare since it is hard to agree on the source of the conflict. An article published in Global Security Review, "What is Hybrid Warfare?" compares the notion of hybrid warfare to the Russian concept of "non-linear" warfare, which it defines as the deployment of "conventional and irregular military forces in conjunction with psychological, economic, political, and cyber assaults." The article partially attributes the difficulty to the "rigid" or static military taxonomy used by NATO to define the very concept of warfare. To counter a hybrid threat, hard power is often insufficient. Often, the conflict evolves under the radar, and even a "rapid" response turns out to be too late. Overwhelming force is an insufficient deterrent. Many traditional militaries lack the flexibility to shift tactics, priorities, and objectives constantly.
