In this article, Chief Warrant Officer Three Darius J. Cooper argues that additive manufacturing (3D printing) represents a transformative capability for the U.S. Army Engineer Regiment in multidomain operations against near-peer adversaries. He contends that 3D printing technology can provide engineer units with a decisive tactical advantage by enabling rapid production of obstacles, structures, and maintenance parts directly on the battlefield, thereby reducing logistical dependencies. However, Cooper acknowledges that realizing this potential requires the Army to address critical challenges including cybersecurity vulnerabilities, material limitations, and the complexities of protecting high-value printing equipment in contested environments. 

This article highlights the critical need for the Engineer Regiment to prepare for operations in extreme cold environments, emphasizing that both soldiers and equipment face unique and severe challenges in such conditions. Drawing on historical and modern examples, it argues that cold-region expertise and training are essential for maintaining combat effectiveness and gaining a strategic advantage. The article calls for updated doctrine and focused training to ensure engineer units are ready to operate where both the enemy and the environment pose lethal threats.
