Decoding Hybrid War Expert Frank Hoffman

Frank Hoffman occupies a specific niche inside the U.S. national security ecosystem. He is not primarily a regional expert like Michael Eisenstadt and not a political advocate like think tank policy entrepreneurs. His role is conceptual architect. His main contribution is the concept of hybrid warfare, which holds that modern adversaries rarely fight in a single mode. Instead, they blend multiple forms of conflict at the same time: conventional military force, guerrilla warfare, terrorism, cyber operations, criminal activity, and information warfare. The innovation is the argument that these elements are not separate phases of war. They run simultaneously. That fusion creates problems for Western militaries built around clean categories.
Hoffman developed the idea during the 2000s after watching conflicts that did not fit traditional military models. Hezbollah’s war with Israel in 2006 was a major influence. Hezbollah combined anti-tank missiles, disciplined infantry tactics, guerrilla operations, media propaganda, and political governance. It behaved partly like an army and partly like an insurgency. Western doctrine at the time assumed enemies would look like one or the other. Hoffman argued that assumption was obsolete.
The concept spread quickly through defense institutions because it explained several contemporary conflicts: Hezbollah in Lebanon, Russian operations in Crimea and eastern Ukraine, Iran’s proxy networks in the Middle East, and ISIS blending insurgency with governance. It gave military planners language to describe what they were encountering. Hoffman writes like a Marine officer who became a strategist. His work is analytical but practical. He focuses on how doctrine and force structure must change rather than engaging in abstract theory.
He also emphasizes that hybrid warfare is not just a military problem but a whole-of-government problem. Because the threats involve criminal activity and information warfare, military force alone cannot solve them. This pushed the U.S. toward concepts like integrated deterrence. Hoffman focuses heavily on the blurring of the line between peace and war. The traditional binary is no longer useful, he argues. Technology now allows small groups to possess lethality previously reserved for nations, which creates a state of perpetual competition.
Hybrid warfare creates a structural problem for advanced militaries. Western forces excel at defeating conventional armies, and they developed counterinsurgency doctrines for guerrilla conflicts. Hybrid adversaries deliberately mix both. They fight conventionally when strong. They disperse into irregular networks when weak. They use terrorism or information warfare to offset battlefield losses. This forces Western planners into constant adaptation.
Of late, Hoffman has focused on the upcoming 2026 National Defense Strategy and a critique of current Pentagon force-sizing models. His recent work argues that the United States faces a defense planning crisis where the cost of its strategic goals far exceeds its available resources. He argues that the Pentagon must abandon the traditional two-theater war construct, the idea that the U.S. should be able to fight two major regional wars at the same time. He views this as financially and strategically unsustainable given the national debt and the rise of what he calls the Axis of Upheaval: Russia, China, Iran, and North Korea.
In its place he proposes Mission-Based Planning, which orders priorities as follows. First, defend the homeland by protecting critical infrastructure from cyberattacks and physical disruption. Second, deter aggression in Asia by working with allies to contain China. Third, modernize the strategic deterrent, including a reconsideration of whether all three legs of the nuclear triad remain affordable. Fourth, conduct unconventional warfare through counterterrorism and security assistance. Fifth, deter aggression in Europe in coordination with NATO.
A major theme in his 2026 commentary is that the U.S. homeland is no longer a sanctuary. He argues that the true second front of any future conflict with the Axis of Upheaval will be domestic critical infrastructure. Chinese and Russian penetration of telecommunications, power, and water utilities amounts to operational preparation of the battlefield. Protecting those domestic assets is now a primary military mission, not a civilian afterthought.
On Iran specifically, Hoffman observes a significant shift. Iran is weaker and more vulnerable than it has been in decades following intense military pressure over the past year. But that vulnerability might increase rather than reduce its reliance on hybrid tactics. Hoffman argues Iran will double down on militant proxies even as proxy inventories are depleted, on the threat of closing the Strait of Hormuz to offset its weakened conventional position, and on a war of attrition rather than the decisive large-scale combat operations Western planners prefer.
Inside the national security ecosystem, Hoffman fills the role of theory provider. Operational analysts like Eisenstadt describe specific threats. Policy advocates argue for particular strategies. Hoffman supplies the conceptual framework that explains why those threats are difficult. Eisenstadt’s work on Iranian strategy often reflects that framework. Iran uses ballistic missiles, proxy militias, cyber attacks, terrorist networks, and political influence operations, which is precisely the mix Hoffman described. Eisenstadt analyzes the specific case. Hoffman explains the general pattern. Together they form part of the intellectual toolkit the U.S. security community uses to understand modern conflict. Hoffman’s influence operates not through media appearances but through doctrine, training, and strategic education at institutions like the National Defense University and the war colleges, where it shapes how officers think about conflict before they encounter it.
