USA Army 3rd Engineer Special Brigade Third Anniversary Poster (1945)
 
Commanded for almost the entire war by Colonel David Ayres Depue Ogden, who was promoted to brigadier general on 18 September 1942, the 3rd Engineer Amphibian Brigade was activated at Camp Edwards on 6 August 1942 with the 533rd Engineer Shore Regiment and 593rd Engineer Boat Regiment assigned.
 
 On 9 November, they became engineer amphibian regiments, and the 543rd Engineer Amphibian Regiment was assigned to the brigade. The brigade moved to Camp Gordon Johnston by rail in November.
 
 In April 1943 it relocated to Fort Ord, where it prepared to move to Australia. Due to shipping shortages and changes in priorities, this took six months.
 
 The brigade was redesignated the 3rd Engineer Special Brigade on 25 May 1943, and the amphibian regiments became engineer boats and shore regiments.
 
The first unit of the brigade to reach New Guinea was the 563rd Engineer Boat Maintenance Battalion, which arrived at Milne Bay on 14 October 1943; the rest of the brigade followed in December 1943 and January 1944. The brigade became widely scattered, and never operated as a single unit, but Ogden retained control using a special radio net.
 
 It participated in the landings at Talasea, Aitape, Lingayen, and Borneo and Mindanao. The brigade returned to the United States on 20 December 1945, and was inactivated two days later.
