In 1967, with the Vietnam War escalating under the Johnson Administration, the U.S Naval Reserve Construction Battalion (SEABEEs), based at Sioux City Naval Reserve Training Center, was called to active duty and deployed as part of Naval Construction Battalion (NCB) 2 to Danang, South Vietnam. These Sioux City Navy men frequently served under direct enemy sniper and artillery fire while engaged in building bases for the Navy and Marine Corps in the Danang area during their 13-month deployment. They served bravely, suffered casualties and returned with honor to their peacetime jobs as Sioux City construction men.
