U.S. servicemen flush and scrub down a newly laid pipeline on a concrete apron amid a coconut grove on Luzon, Philippines, during World War II. Scenes such as this were common during the 1944-1945 liberation campaign, when Army engineer and Navy construction battalion (Seabee) units raced to build and maintain the airfields, fuel lines, and base infrastructure that sustained Allied air and ground operations in the Pacific Theater.
