Force structure, readiness, power projection, and deterrence: the Bureau’s strategic assessment of Mexico’s military capability — scored 0–100 across 24 causal dimensions.
The 45.06/100 rests first on Combat experience (75.00), Force mass (71.75), Readiness & training (70.00). The binding constraints: Air power (8.00), Submarine force (8.00), Nuclear survivability (6.50) — in a causal model, capability can never rise above its weakest observed link. What would move the needle: Air power (8.00) — the weak link in the spending → equipment → readiness → capability chain.
2 of 24 dimensions could not be observed (Missile forces, Air defense); missing data caps the score — it never inflates it.
Assessment coverage: 95.7% — 22 of 24 dimensions observed. Kernel v10, run 2026-10-04; evidence snapshot: CIA World Factbook 2026-09-28, SIPRI arms-producer revenue, v9 nuclear taxonomy.
Kernel assessment: Air power 8.00/100 (observed).
Type-by-type inventory in preparation — this dossier deepens as coverage grows. Nothing here is estimated silently.
Kernel assessment: Land warfare 68.81/100 (observed).

Kernel assessment: Naval power 35.40/100 (observed).
Type-by-type inventory in preparation — this dossier deepens as coverage grows. Nothing here is estimated silently.
Missile forces could not be observed in this assessment — missing data caps the score, it is never treated as zero.

Status: non-nuclear-weapon state
the Mexican Armed Forces (Fuerzas Armadas de México) are divided between the Secretariat of National Defense and the Secretariat of the Navy: Secretariat of National Defense (Secretaria de Defensa Nacional, SEDENA): Army (Ejercito), Mexican Air Force (Fuerza Aerea Mexicana, FAM), National Guard (Guardia Nacional); Secretariat of the Navy (Secretaria de Marina, SEMAR): Mexican Navy (Armada de Mexico (ARM), includes Naval Air Force (FAN), Mexican Naval Infantry Corps (Cuerpo de Infanteria de Marina, Mexmar or CIM)) Secretariat of Security and Civilian Protection/SEDENA: National Guard (2025)
information varies; approximately 260,000 active-duty Armed Forces; approximately 110,000 National Guard personnel (2025)
the Mexican military inventory includes a mix of domestically produced and imported armaments from a variety of mostly Western suppliers, particularly the US; Mexico's defense industry produces light armored vehicles and some naval vessels, as well as small arms and other miscellaneous equipment (2025)
18 years of age (16 with parental consent) for voluntary service for men and women; men at age 18 subject to lottery-based 12-month compulsory military service (2025)
the Mexican military is responsible for defending the independence, integrity, and sovereignty of Mexico, as well as providing for internal security, disaster response, humanitarian assistance, and socio-economic development; internal security duties are a key focus, particularly combating narcotics trafficking and organized crime groups, as well as border control and immigration enforcement; the constitution was amended in 2019 to grant the president the authority to use the armed forces to protect internal and national security, and courts have upheld the legality of the armed forces’ role in law enforcement activities in support of civilian authorities through 2028; the military also provides security for strategic facilities, such as oil production infrastructure, and administers most of the country's land and sea ports and customs services, plus a state-owned development bank; in addition, President LÓPEZ OBRADOR placed the military in charge of a growing number of infrastructure projects, such as building and operating a new airport for Mexico City and sections of a train line in the country’s southeast (2025)
MILITARY POWER 45.06/100 — The Magna Military Power score is our 0–100 measure of causal military capability — 24 dimensions (mass, equipment, readiness, projection, industry, nuclear deterrence), aggregated through a dependency graph, never by simple addition.
Momentum +3 — Quarterly momentum: the Bureau's read on the country's trajectory over the last quarter, from −10 (deteriorating fast) to +10 (accelerating).
Mexico navigated US tariff pressure inside the USMCA framework without breaking the relationship — the quarter's central test, passed.
Behind the diplomacy, the fundamentals held: record first-half FDI and falling homicides. A modestly positive quarter for a country managing a giant neighbour.
