Exploiting Fragmentation: An Economy of Force SOF Strategy Against Iran’s Proxy Network
Abstract
Operation Epic Fury has fragmented Iran’s proxy network, creating a narrow window for the United States to disrupt Tehran’s influence while exposing the risks of overcommitting high-demand Special Operations Forces (SOF) amid competing National Defense Strategy priorities. This paper argues that a strategic economy of force approach – centered on SOF-enabled partner operations, intelligence-driven network targeting, and limited, high-threshold U.S. direct-action missions – can exploit this opportunity while preserving readiness and global flexibility. Ultimately, it contends that prioritizing efficiency and indirect methods over a U.S.-led direct-action campaign best aligns tactical gains in the Middle East with long-term strategic objectives.
Operation Epic Fury has introduced a strategic inflection point in the conflict with Iran, forcing the Department of War (DoW) to balance emergent operational requirements in the Middle East against competing mandates in the National Defense Strategy (NDS), specifically strategic competition and Western Hemisphere security. Simultaneously, the operation is destabilizing Iran’s proxy forces and exposing critical vulnerabilities in Tehran’s control mechanisms over the Axis of Resistance. This evolving landscape presents a transient opportunity for the United States to further disrupt Iranian influence, but also raises a fundamental question: how to exploit this window without overcommitting high-demand resources—particularly Special Operations Forces (SOF)—in ways that undermine broader national priorities? Resolving this dilemma means following the administration’s stated objectives for the operations – treating proxy network disruption as a supporting effort and executing disciplined force allocation.
SOF possess the unique capabilities required to dismantle Iran’s compartmentalized proxy networks; however, SOF employment carries significant opportunity costs, requiring the DoW to balance immediate regional demands against global requirements. Accordingly, SOF employment must be carefully calibrated to exploit proxy fragmentation without degrading readiness for higher priority contingencies in other theaters. The United States must therefore adopt an economy of force approach that prioritizes SOF-enabled partner operations, intelligence-driven network targeting, and limited U.S. direct-action missions. By shifting from a U.S.-led kinetic model toward partner-enabled campaigns, the United States can sustain pressure on Iran’s fragmented proxy network while avoiding overextension of limited SOF resources. This shift ensures tactical opportunities in the Middle East remain aligned with long-term national security objectives.
Iran’s Proxy Network After Epic Fury: Fragmentation and Opportunity
For decades, Iran has cultivated an extensive network of non-state allies and proxy forces to offset its conventional military limitations and mitigate the effects of isolation. This “Axis of Resistance” links predominantly Shia militant organizations aligned against Israel, Saudi Arabia, and Western powers. Orchestrated by the Islamic Revolutionary Guard Corps–Quds Force (IRGC-QF), this system enabled Tehran to project influence while maintaining plausible deniability. By 2020, this network fielded nearly 200,000 fighters across the Middle East and Central Asia.
This model of warfare presents inherent challenges for conventional military forces. Iranian proxies operate through clandestine networks and irregular tactics, often embedding within civilian populations. These activities—ranging from unmanned systems employment to political subversion—remain below the threshold of armed conflict while imposing persistent costs on their adversaries. Consequently, large-scale conventional units are ill-suited to counter such threats effectively. Efforts to employ conventional forces against these networks risk inefficiency, as diffuse threat environments require a network-centric response that they cannot easily integrate into their doctrine.
While Operation Epic Fury successfully disrupted Iran’s conventional military infrastructure and degraded IRGC-QF command-and-control nodes, it did not eliminate the proxy architecture. Instead, the network has undergone a forced evolution, fracturing from a centralized hierarchy into semi-autonomous, local actors. This fragmentation has temporarily severed Tehran’s ability to synchronize strategic effects across multiple theaters, leaving these proxies in a state of disorganized vulnerability. However, this shift also signals a dangerous transition: As these groups adapt to the lack of centralized oversight, they are becoming increasingly independent, pursuing localized objectives and legitimacy.
This transitional phase creates a critical, fleeting window of opportunity. Currently, the loss of Iranian “connective tissue” has spiked coordination costs and intensified competition for resources, exposing vulnerabilities ripe for exploitation. Yet, the window is closing. As these proxies evolve into fully autonomous entities, they will become more unpredictable and harder to deter through traditional state-based pressure. To be effective, intervention must capitalize on this disarray with a force posture optimized for irregular warfare rather than large-scale combat operations.
The SOF Allocation Problem: Persistent Demand and Strategic Overextension
Joint Publication 3-05 emphasizes that SOF should be used in prioritized roles rather than as a substitute for conventional capacity. In practice, however, SOF employment since the Global War on Terror (GWOT) has diverged from this ideal. SOF evolved into a routinely employed force serving as the main effort across multiple, simultaneous theaters. To meet these requirements, USSOCOM expanded from 45,700 in 2001 to nearly 73,900 personnel by 2021, yet this growth failed to resolve the underlying strain. SOF personnel deployed at rates significantly higher than conventional counterparts, and demand for key enablers consistently exceeded supply. These trends reflect a force that has become a ubiquitous instrument of national power rather than a prioritized strategic asset.
Recent congressional testimony suggests this divergence has intensified. In March 2026, Admiral Frank Bradley, Commander of USSOCOM, warned that demand for SOF has surged 300 percent over the past five years, creating a crisis of “growing usage but diminishing resources.” Critically, Bradley noted that USSOCOM is now forced to “eat into its modernization budget to cash flow current operations,” effectively trading long-term capability for near-term requirements. These dynamics indicate that SOF is structurally overcommitted, operating at a level that exceeds both its capacity and its ability to prepare for future conflict.
The GWOT era serves as a cautionary precedent regarding sustained overcommitment. Although large-scale counterterrorism campaigns have diminished, global demand for SOF remains high. Operation Epic Fury introduces an unanticipated demand signal that threatens to exacerbate this cycle. Without rigorous prioritization, the pivot toward countering Iranian proxies risks diverting low-density SOF assets from the higher-priority theaters mandated by the NDS. Such a shift would dilute U.S. strategic focus and risk degrading readiness for a force that remains limited. The challenge is to exploit tactical opportunities without institutionalizing patterns of strategic overextension.
Economy of Force as Strategy, Not Constraint
The principle of economy of force dictates that commanders must allocate “minimum essential combat power to secondary efforts” to mass effects at decisive points. While traditionally an operational consideration, economy of force is now a strategic mandate driven by the National Security Strategy’s (NSS) requirement to discipline global commitments. The NSS explicitly warns that “sustained attention to the periphery is a mistake,” establishing a hierarchy that prioritizes core interests over regional entanglements. Concurrently, the NDS directs the Joint Force to remain “laser-focused” on homeland defense and Indo-Pacific deterrence.
Within this framework, Operation Epic Fury remains subordinate to strategic competition and Western Hemisphere security. The friction between operational demands in the Middle East and NDS priorities creates a structural misalignment for SOF. As articulated in Army Doctrine Publication 3-0, economy of force centers on accepting prudent risks in secondary theaters to preserve power for decisive efforts. Strategically, this necessitates an approach to Epic Fury that minimizes SOF commitment while sustaining disruptive effects against Iranian proxy remnants.
SOF are the primary instrument for operationalizing economy of force. By prioritizing Special Warfare—specifically the cultivation of indigenous partners and intelligence-driven targeting—SOF can generate disproportionate effects with a minimal footprint. This model mitigates threats posed by the residual Axis of Resistance without eroding the modernization capital required for higher priority national policy objectives.
SOF Enabled Partner Operations: Leveraging Indigenous Capacity
To operationalize the “strategic window” created by Epic Fury, the United States must transition from U.S.-led kinetic operations to a Special Warfare posture centered on indigenous capacity. The primary mechanism for this is the optimization of 10 U.S.C. § 127e (Support of Special Operations to Combat Terrorism) authorities. While § 127e is the principal tool for coordinating with surrogate forces—including vetted non-state actors like the Syrian Democratic Forces—its utility is maximized when synchronized with 10 U.S.C. § 333 (Foreign Security Forces: Authority to Build Capacity). This “build-to-employ” framework utilizes § 333 to institutionalize foundational capabilities—logistics, medical, and small unit tactics—while employing § 127e to direct those units in high-priority interdiction missions.
Analysis of § 127e programs in the Levant demonstrates the significant return on this economy of force model. USSOCOM leadership has consistently validated these authorities in congressional testimony, with ADM William McRaven labeling § 127e “the single most important authority” in counterterrorism, while Generals Raymond Thomas and Richard Clarke credited the program with providing the unique access necessary to capture or kill thousands of terrorists. In practice, this allows SOF to penetrate compartmentalized networks where conventional forces lack access. By leveraging the local legitimacy of indigenous partners, § 127e functions as a force multiplier, extending reach while reducing requirements for a sustained U.S. presence.
When paired with § 333 authorities to build durable capacity, this model provides a scalable framework for countering proxy organizations at their source. It distributes the operational burden, enhances partner legitimacy, and creates sustainable security solutions. Ultimately, this approach aligns execution with strategic prioritization, ensuring regional requirements do not degrade USSOCOM’s capacity to meet NDS mandates.
Intelligence Driven Network Targeting: Disrupting Cohesion and Control
While leveraging indigenous capacity addresses the physical presence of proxies, USSOCOM must also sever the operational lifelines sustaining their activity. This requires a complementary model prioritizing the disruption of financial and logistical networks. The targeted degradation of these nodes does not merely attrit the force; it can degrade or, in some cases, collapse organizational cohesion.
Central to this is the interdiction of Tehran’s funding, which funneled over $1 billion to Hezbollah in 2025 despite extensive international sanctions. Depriving organizations of reliable funding limits procurement and strikes at their ability to recruit and retain fighters. Empirical studies identify a terrorist group’s peak organizational size as the primary determinant of its longevity and success. For fighters motivated by salary, the evaporation of revenue accelerates organizational atrophy. Iranian proxy networks, however, are additionally sustained through a complex system of illicit trafficking and transnational facilitation networks. Effectively disrupting these interconnected nodes will require a coordinated interagency approach.
SOF, with interagency partners, must integrate intelligence, cyber, and law enforcement capabilities to exploit vulnerabilities across proxy sustainment networks. This includes targeting financial flows, logistics hubs, and data networks. Through enhanced collection—combining human intelligence from partners with signals intelligence and digital financial access—SOF can illuminate otherwise opaque networks and expose nodes for interdiction. Interagency collaboration, particularly with the Treasury and Intelligence Community, further enables cooperative access to operations. Targeting sustainment nodes disrupts the material foundation required for proxy organizations, limiting their ability to function as a coherent organization.
Crucially, this model maximizes the efficiency of low-density assets. Intelligence-driven operations enable precision engagements that impose asymmetric costs. When integrated with § 127e-enabled partner operations, intelligence is rapidly translated into action by surrogate forces capable of executing missions with negligible U.S. presence. This fusion sustains pressure on Iranian networks while insulating high-demand SOF resources from overextension.
Limited U.S. Direct-Action: Precision Over Presence
An economy of force approach does not eliminate the requirement for U.S. direct action; rather, it defines the conditions for its employment. A limited but credible direct-action capability remains essential for time-sensitive, high-consequence threats that exceed partner capacity. These networks continue to pose a direct and evolving threat to the United States, American citizens abroad, and regional allies. Even fragmented, Iranian proxies retain the intent and capability to conduct attacks on diplomatic facilities, U.S. military bases, and partner nation infrastructure. The United States must retain a forward-deployed, rapidly employable capability to protect U.S. persons and neutralize high-risk actors.
Forward-deployed SOF elements—regionally postured and low-signature—provide the foundation for this posture. These forces enable immediate response to emerging contingencies while maintaining persistent situational awareness of their operating environment. Additionally, USSOCOM must retain the ability to rapidly deploy SOF from the continental United States to augment theater forces during periods of elevated risk. This scalable model preserves flexibility while avoiding the high fixed costs of a robust deployed force.
Within this framework, direct action should be reserved for scenarios aligning with strategic priorities: hostage rescue, WMD render-safe operations, or precision raids against high-value individuals posing imminent threats. By constraining direct action to clearly defined objectives, the U.S. ensures its most capable forces are employed for decisive effects. Establishing explicit mission approval thresholds ensures capabilities remain integrated within a broader campaign design.
The (Misguided) Allure of a Direct-Action Campaign
A U.S.-led direct-action campaign offers a compelling case rooted in speed and precision. More than two decades of conflict have refined SOF into a premier instrument for dismantling insurgent organizations. The Joint Special Operations Command’s (JSOC) campaign against al-Qaida in Iraq (AQI) provides a prominent example. At its peak in 2006, AQI fielded 15,000 fighters, generated $8 million a month through extortion, and operated a shadow governance structure. JSOC’s largely unilateral, intelligence-driven raids against AQI’s leadership and sustainment nodes degraded the network to approximately 800 fighters by 2011. JSOC rendered the once prominent and influential organization impotent, unable to coordinate large-scale attacks or maintain territorial control.
This model is particularly applicable to Iranian proxy forces, which, like AQI, operate in compartmentalized cells. Precision strikes against facilitators and traffickers can produce cascading effects across the network. Moreover, U.S.-led direct action offers a visible demonstration of resolve. Unlike indirect approaches that require time to generate effects, direct action produces immediate, tangible results. Operationally, it offers greater predictability by minimizing variability associated with partner capacity. This centralized model simplifies command-and-control and enables rapid adaptation to emerging intelligence, making it an expedient option for exploiting the initial disarray of Iranian proxy networks.
These factors make a direct-action-heavy campaign intuitively appealing, promising speed and clarity. However, these advantages must be evaluated within the broader strategic context governing SOF employment.
Why Economy of Force Offers the Decisive Advantage
The central question is not whether a direct-action campaign can degrade Iranian proxy networks—it demonstrably can—but whether it represents the optimal allocation of finite resources. Evidence from the post-9/11 era suggests that sustained direct-action campaigns by SOF generate diminishing strategic returns by overshadowing indirect operations that enable foreign security forces.
A direct-action-centric approach maximizes short-term disruption at the expense of strategic flexibility. Such campaigns are resource-intensive, requiring robust intelligence, aviation, and rotational deployments that strain readiness. As Admiral Bradley’s testimony underscores, USSOCOM is operating beyond sustainable capacity. Expanding a U.S.-led campaign in the Middle East would impose costs that undermine preparedness for higher-priority contingencies.
By contrast, an economy of force approach offers a sustainable model. Rather than attempting to decisively eliminate networks, this approach focuses on constraining their ability to reconstitute. SOF-enabled partner operations and intelligence-driven targeting impose friction at a fraction of the cost of unilateral action. The Irregular Warfare Annex to the NDS reinforces the need to leverage partner forces in a “by, with, and through” approach to achieve enduring and cost-effective results.
Ultimately, the economy of force aligns means with ends amid resource constraints. It accepts that Iranian proxy networks do not need to be fully eradicated to achieve U.S. objectives; they must instead be contained and denied the means to generate strategic effects. By prioritizing efficiency, the United States preserves critical capabilities for higher-priority NDS objectives while exploiting the vulnerabilities exposed by Epic Fury. This avoids the trap of allowing tactical success to drive disproportionate commitment.
Conclusion
Operation Epic Fury has created a transient opportunity to degrade Iran’s proxy network. The fragmentation of the Axis of Resistance has disrupted command relationships and introduced instability. Yet this opportunity exists within a strategic environment defined by finite resources. The challenge is exploiting this fragmentation without undermining higher-order objectives. The administration’s focus on Iran’s nuclear and missile capabilities establishes a hierarchy where proxy degradation remains a supporting task. Without disciplined force allocation, operational momentum could drive disproportionate SOF commitment.
An economy of force approach provides the framework to resolve this tension. By prioritizing SOF-enabled partner operations, network targeting, and scoped direct action, the United States can sustain pressure while minimizing its operational footprint. This model aligns tactical execution with strategic priorities, ensuring Middle East efforts do not erode the global responsiveness required for higher-priority contingencies. By resisting a U.S.-led direct-action campaign, the United States exploits vulnerabilities while preserving the flexibility required for long-term competition. This ensures U.S. military power remains aligned with enduring national interests.
