Why US Navy Seabees mattered to the Pacific advance

What are the US Navy Seabees?

They are armed naval construction battalions that build bases and infrastructure in expeditionary conditions, often beginning work while a captured area is still dangerous.

The Seabees are specialized US Navy construction personnel who can land where required and build the infrastructure a force needs. Their work supported the Pacific campaign, including on islands where resistance continued after the initial landing. They carried weapons and could spend weeks fighting while construction proceeded. The familiar claim that Marines won an island and Seabees secured control of it reflects that continuing danger. A later audience contribution adds accounts of Seabees fighting beach defenses while clearing obstacles for following forces.
