The 19th Marine Regiment was a composite engineer regiment of the United States Marine Corps subordinate to the 3rd Marine Division. It existed from September 1942 until September 1944. Marine engineer regiments were eventually disbanded in favor of independent engineering battalions within the parent Marine divisions.
The regiment was a composite of three different types of battalions and a headquarters and service company:
Assigned to the 3rd Marine Division, on 11 March 1943 Col Robert M. Montaque took command of the Regiment in New Zealand. September 1943 saw the regiment land in the assault on Bougainville. From there it went to Guadalcanal in preparation for the invasion of Guam in July 1944. It landed in the assault on Guam and was inactivated on 17 August. The 25th NCB was returned to the Navy and assigned to the 5th Naval Construction Brigade, remaining on Guam until the war ended.
With the inactivation of the 19th Marine Regiment the 3rd Engineer Battalion and the 3rd Pioneer Battalion were posted directly to the 3rd Marine Division. The 25th Naval Construction Battion was replaced by the 62nd Naval Construction Batttlion which was also posted directly to the Division for the assault of Iwo Jima. The 3rd Pioneers landed on yellow 2 beach on D-plus 3 and remained there until D-plus 6. On D-plus 6 black beach was created and the pioneers moved there as did the 3rd Engineers. The 62nd NCB was made the lead Battalion for getting Motoyama Airfield #1 operational in place of the 133rd NCB which had taken heavy casualties.
