Inchon and the scale behind an amphibious landing

The reinforced 1st Marine Division's order of battle reveals the support structure hidden behind the headline assault force. Marine and Navy personnel were joined by a Korean Marine regiment and U.S. Army engineers, artillery, port-construction, signals, ordnance, and amphibious-vehicle units. The nearly 28,000-person initial total, with further troops and administrative organizations en route, demonstrates how engineers, logistics, communications, artillery, armor, and aviation make amphibious combat possible. Some operations require going in heavy rather than relying on a small elite detachment.
