## History
### World War II

The battalion was first formed on 16 September 1942 as 1st Battalion, 19th Marine Regiment. Two years later on 16 August 1944 they were re-designated the 3d Engineer Battalion. The battalion was deactivated at Marine Corps Base Camp Pendleton, California on 30 November 1945. From August 1957 until January 1962, the battalion was designated 3d Pioneer Battalion.

### Vietnam War

The 3d Combat Engineer Battalion deployed to the Republic of Vietnam landed at Chu Lai in July 1965 and later moved to Da Nang remaining in country until October 1969. During this time the battalion operated from Da Nang, Đông Hà, Gia Le, Quang Tri, Cửa Việt, Camp Carroll, Cam Lộ, and the Vandegrift Combat Base. After Vietnam the battalion was moved to Camp Schwab, Okinawa, only to be relocated in November 1970 to Camp Hansen, Okinawa. On 15 May 1976 the battalion was redesignated as the 3d Combat Engineer Battalion.

### 1970s through the 1990s

In September 1975, the Battalion was redesignated as 3d Combat Engineer Battalion.
3d CEB provided three companies to Operations Desert Shield/Desert Storm between August 1990 and March 1991. "Alpha" Company deployed from Marine Corps Base Hawaii with the 1st Marine Expeditionary Brigade, "Bravo" Company deployed via amphibious shipping 15 August 1990 from Okinawa, and "Charlie" Company landed in Saudi Arabia five days before the air war began. The Marines from 3d CEB participated in breaching operations with "Task Force Grizzly" and "Task Force Papa Bear." Once in country, Alpha Co, 3rd CEB was soon assigned to 1st CEB and was referred to as "Alpha 3rd", to distinguish them from Alpha Company, 1st CEB. One platoon from Bravo Company, 3rd CEB, 3rd Mar Div, Okinawa, arrived in country via amphibious shipping and was added to "Alpha 3rd'" to become the company's 3rd platoon. 1st CEB supported Taskforce Ripper, [the lead element of 1st Mar Div during Desert Storm]. "Alpha 3rd'", was designated an Obstacle Clearing Detachment and was assigned to operate along with 1st Battalion 5th Marines, Company A, 3rd Assault Amphibian Battalion and Company A 1st Tank Battalion as the lead element of Task Force Ripper to breach minefields. Alpha Company 3rd' performed one minefield breach on the 1st mine field belt, and one breach on the second minefield breach which was defended by the Iraqi forces. "Alpha Company '3rd" also supplied a squad of engineers to conduct breaching operations for Task Force Shepard.
In 1995, 3d CEB was deactivated. Their numbers were dispersed to other combat engineers units throughout the Marine Corps. The battalion was renamed Combat Engineer Company and was folded into Combat Assault Battalion of the 3rd Marine Division.

The company, minus its 2nd Platoon, deployed to Iraq in support of Operation Iraqi Freedom and fell under the command of Regimental Combat Team 5 during 2008.
