Proxy arming: the covert supply chains that sustain today's wars

What it is

Proxy arming covers how external states and transnational networks supply weapons, financing, and personnel to armed groups or allied belligerents without committing their own forces openly. The mechanism has three elements: a sponsor (usually a state or state-backed entity), a channel (intermediaries, front companies, re-export hubs, or covert cargo routes), and a recipient (a militia, insurgency, or allied government). Sponsors gain strategic leverage while maintaining plausible deniability, particularly when the arming violates UN arms embargoes, bilateral assurances, or the sponsor's own export-control laws. The beat sits at the intersection of armed conflict, shadow economy, and sanctions enforcement. Research consistently shows external arming is the factor most strongly correlated with conflict duration: civil wars backed by outside powers last, on average, three times longer than those without.

History

The Cold War institutionalized proxy arming globally. The United States armed Afghan mujahideen through Pakistan's ISI from 1979; the Soviet Union supplied North Vietnam through China and Laos. After 1991, the mechanism did not disappear but became harder to attribute cleanly. The 2011 NATO intervention in Libya dispersed Muammar Gaddafi's stockpiles across the Sahel, fueling insurgencies in Mali, Niger, and Chad. Iran's Islamic Revolutionary Guard Corps built its Axis of Resistance from the early 1980s, arming Hezbollah in Lebanon, then Yemen's Houthi movement with ballistic missiles, anti-ship weapons, and drone components. Russia's deniable arming of Donbas separatists from 2014, through unmarked deliveries and front operators, set a template both sides studied for Ukraine. The 2023 eruption of Sudan's civil war and the October 7, 2023 Hamas attack on Israel each opened fresh arming cycles across multiple fronts.

Current state

As of July 2026, proxy arming operates in at least seven active conflict theaters. The most publicly documented 2026 case is the United Arab Emirates' supply chain to Sudan's Rapid Support Forces, routed via Ethiopia and four identified military camps in eastern Libya: Seweidiya near al-Kufra, Sabha, al-Jufra, and Camp 17 outside Benghazi (see 阿联酋将向苏丹快速支援部队的武器空运航路改道，经由埃塞俄比亚中转 and 调查报道绘制出利比亚境内四处UAE支持的快速支援部队训练营，配有哥伦比亚和俄罗斯人员). An RSF spokesman acknowledged in June 2026: "The Emirates gave it to us." Iran continues supplying Yemen's Houthis with anti-ship missiles and Shahed-series drone components despite a UN arms embargo and ongoing US naval interdiction. Russia's Africa Corps maintains supply chains to governments in Mali, Burkina Faso, and Libya's LNA under Khalifa Haftar, as well as Sudan's Sudanese Armed Forces. Colombia supplied mercenary fighters to RSF camps in Libya as of June 2026, adding a new foreign-fighter dimension. Ukraine, until 2026 the world's largest single arms-aid recipient, opened controlled weapons exports to 27 Drone Deal partner countries in July 2026, completing a circle: the largest recipient became a supplier (see 乌克兰自2022年入侵以来首次开放受控武器出口).

Relationships

The UAE's Sudan supply network runs through Libya, linking it directly to Haftar's LNA, which hosts Camp 17. Russia's Africa Corps infrastructure overlaps with the Libyan camps serving the RSF, tying the Sudan and Libya theaters into a single logistics corridor. Iran's channel flexibility is constrained by the US-Iran Doha nuclear framework reached in early July 2026: if the agreement holds and includes verified arms-export provisions, the Houthi supply chain faces its first genuine constraint. Ukraine's new export mechanism creates a competing drone-and-counter-UAS supply axis, a direct commercial response to Russian drone proliferation across conflict zones. SIPRI's March 2026 data recorded global major arms transfers in 2021-25 at 9.2 percent above the prior five-year period, with the United States holding a 42 percent export share, followed by France and Russia.

What to watch

• Whether US Treasury sanctions, which in June 2026 targeted Colombian-fighter recruitment networks supplying the RSF, expand to cover UAE cargo operators and the Libya camp infrastructure directly.
• The UN Panel of Experts on Sudan: its reconstitution is overdue. First reporting will be the most authoritative public accounting of the RSF supply chain since the war began in April 2023.
• Iran's arms-export posture after the Doha framework. A verified arms-export clause would be the first real constraint on the Houthi supply chain, shaping Red Sea security through 2027.
• SIPRI's next annual arms-transfers fact sheet (expected March 2027), which will capture the first full year of Ukraine's export programme and whether Gulf-state buyers under the July 2026 bilateral deals emerge as significant import customers.
