Should the U.S. increase investment in military infrastructure across the Pacific for regional defense?
On October 7, the U.S. Army released a 46-page manual titled How the Army Fights, outlining hypothetical high-intensity conflict scenarios. The document includes a study of Operation Iron Gateway, which explores the impact of a tactical nuclear strike on logistics airfields in Guam.
Why it matters
The manual aims to prepare the military for potential contested high-intensity conflicts in the Pacific region. It outlines strategies to optimize a mobile and sustainable footprint while addressing logistical throughput disruptions during extreme combat events.
The manual utilizes 46 pages of tactical modeling to analyze nuclear effects, including a radioactive fallout range of 50 to 200 kilometers. It notes that 90% of this radiation decays within 48 hours, a metric used to plan decontamination timelines.
The players
United States Army
The branch of the United States Armed Forces responsible for land-based military operations.
The details
The document details how the Army leverages engineer assets and dispersed forces to harden infrastructure against nuclear effects. It specifically identifies Andersen Air Force Base and A.B. Won Pat International Airport as sites requiring logistical resilience plans.
Timeline
October 7, 2026: The Army released the warfighting manual.
72 hours: The duration of logistics disruption following a nuclear strike.
48 hours: The time required for 90% of nuclear fallout to decay.
Two weeks: The target time required to restore logistical throughput.
The Big Picture
This document extends the strategic objectives established under the Pacific Deterrence Initiative. By modeling nuclear strike outcomes, the Army shifts its operational focus toward hardening distribution networks and forward-deploying engineering assets to maintain stability.
The Army plans to expand protected fuel and munitions storage across the second island chain to ensure long-term regional stability. These infrastructure projects prioritize forward-deployed engineering and medical assets to harden the regional supply chain.
The takeaway
The manual underscores a military pivot toward maintaining operational mobility in environments where conventional logistics might be severed. It emphasizes that hardening infrastructure and training decontamination teams are essential components of modern high-intensity conflict readiness.
