The Death Ride of the Armor Branch
LTC (R) Amos Fox, Ph.D. of Small Wars Journal provides a critical assessment of modern mechanized warfare in his article, Maneuvering to Obsolescence: The Death Rite of the Armor Branch. The piece was published in Small Wars Journal on July 13, 2026.
This podcast explores the institutional and tactical shifts necessary to prevent the obsolescence of the United States Army Armor branch.
Strategic Representation and Advocacy
The Armor branch currently maintains its smallest level of representation within the operational force in its history. Dedicated armor positions are concentrated in only four divisions, including the 1st Cavalry and the 1st, 3rd, and 1st Armored Divisions. This physical contraction is compounded by a loss of institutional influence. The transition of the Armor Commandant from a two star to a one star position has resulted in a diminished seat at senior leadership tables. The branch has also lacked four star general representation for several years. These factors limit the ability of the community to advocate for force structure and command billets against competing priorities.
The Problem of Movement and the Air Ground Littoral
The primary challenge in modern warfare is the ability to move under conditions of total battlefield transparency. Information technology, drones, and long range precision strikes have curtailed traditional movement. The air ground littoral now represents the decisive space that armored forces must control to remain viable. Reliance on the M1 Abrams as the centerpiece of the formation is increasingly difficult. This is due to its weight and the proliferation of top attack threats. Future survival depends on developing lighter, faster platforms. These platforms must prioritize protection from aerial threats and anti tank guided missiles over direct fire protection.
Narrative and Force Structure Adaptations
Current armor narratives often rely on nostalgia and historical examples from the 1973 Arab Israeli War or the 1991 Gulf War. These frameworks fail to account for the explosion of global urbanization which forces mechanized units into dense, positional environments. The branch must transition its identity toward becoming a second echelon force focused on exploitation. This role involves acting as a catalytic component that converts initial success into victory by moving through fleeting windows of opportunity. Force structure must adapt to manipulate data and tempo rather than just providing additive technological upgrades to existing units.
Cultivating Conceptual Leadership
The military institution frequently prioritizes tactical execution over creative thinking. This bias has left the armor community unable to craft compelling arguments that resonate with the joint force and combatant commands. Institutional survival requires a champion who can articulate a vision of mechanized warfare that meets the requirements of the Department of Defense. The community needs to empower junior and mid level leaders to push for radical reform. Success in future conflicts depends on experts who understand mechanized land warfare through the lens of the air ground littoral and restored mobility.
