The U.S. Navy Seabee Museum has recently acquired a scaled model of a wooden timber bunker for its permanent collection. Donor John O’Brien served with MCB 10 as a 3rd class Builder Heavy (BUH3) and was a member of Detail KILO. John O’Brien recreated this timber bunker based on a U.S. Navy photograph he received before departing MCB 10 in 1968. According to Mr. O’Brien, over 30 of these bunkers were built and assembled by breaking the men into groups of 4 to accomplish a certain task on each bunker before moving on to the next.

The men of Mobile Construction Battalion 10 (MCB 10), who are commonly referred to as the “Men of Ten”, accomplished many courageous tasks while deployed during the Vietnam Conflict. Their third deployment to Vietnam in 1967-68 was unique because it was the first time that the battalion had been so widely dispersed rather than keeping them together. Construction detail crews were spread across South Vietnam, just south of the Demilitarized Zone (DMZ) dividing North and South Vietnam. The DMZ ran east to west along the Ben Hai River near the 17th parallel and extended 5 kilometers on each side of the river.

According to MCB 10’s cruise book, Delta Company, consisting primarily of builders and steelworkers, was one of two general construction companies in the battalion. Its function was vertical construction, such as steel and wooden frame buildings, bridges and revetments (retaining walls). Because of widely spread construction sites, the company was broken down into smaller details.

Detail INDIA departed Gia Le for Phu Bai on September 28, 1967 to construct living quarters for the First Marine Air Wing. Work was well underway; when Detail INDIA was disbanded on November 2, 1967 due to the need for Seabees to preform higher priority work near the DMZ, in the I Corps area. The I Corps encompassed the five northernmost provinces in South Vietnam. Detail KILO was established on the same day, November 2, 1967, to complete heavy timber ammo and personnel bunkers at Cam Lo for the Marines. Their mission was completed in just over thirty days, eleven days ahead of schedule. Detail KILO returned to base camp on December 18, 1967 where the battalion regrouped and continued to work throughout the remainder of the deployment to change a sand-surrounded airstrip site at Quang Tri into a sprawling military complex.

Mr. O’Brien recalled his commander of Detail KILO, LTJG Phillip Crocket, challenging the crews to catch up with the crew ahead of them by claiming the crew was already done and enjoying a beer. If they caught up with them, they could rest and have a beer too. Crockets motivational plan worked to complete the project in record time, although no one rested until the completion of the project.

According the Commanding Officer of MCB 10, D.A. Bartley, he said “it was an interesting and rewarding deployment not only from the standpoint of the construction accomplishment, but also from the accolades received from our ‘customers’, the Marines and Army, for [the battalions] outstanding performance, devotion and dedication to duty.”

Come to the museum on August 2, 2016 2-4pm and learn more about the timber bunker and other behind the scene collections at the U.S. Navy Seabee Museum.

Archivist Attic – Acey Bone at Incheon

In September 1950 the personnel and equipment of Acey Bone (ACBONE), the familiar name of Amphibious Construction Battalion ONE, participated in the invasion of Inchon, Korea. This decisive victory turned the tide in favor of the United Nations and enabled the recapture of Seoul, South Korea, a few weeks later. Acey Bone was able to set up piers, a tent city, and even provide entertainment, quicker than you can get through your holiday celebrations!

On the morning of September 15th, the Marine Landing Force made its assault at Inchon. The Seabees were right on their heels and one and a half hours after the first waves hit the beach the Seabees had the pontoon cause way launched, assembled, and ready for beaching.

Natural obstacles proved the biggest test for building the harbor. Tidal flats and extreme tides led to maximum tidal currents against which the causeway could not be maneuvered. Working against time and tide, the pier was installed after two unsuccessful attempts. Placement of the pier had to be carefully planned in order to provide constant accessibility during both high and low tides.

Even with all the Seabee ingenuity, tidal conditions continued to limit operations. To combat this, small crafts were employed to maintain a constant flow of materials across the pier. The combination of pier work and small craft permitted 24-hour utilization of the vital links.

While pontoons were being placed in the harbor, the beach conditions were also being improved in order to make a workable base. A tent city was constructed while drivers improved roads improving the flow of materials. Seabees with railroad experience also brought Korean locomotives through enemy mortar and fire to supply the troops. They manned this equipment for the duration of their stay. Their fortitude and unusual skill provided unexpected service in support of the logistic operations.

All work and no play makes even the best military cranky. No problem with that though, the Seabees took care of that when they installed a theater. The theater proved so popular that once again, the traditional “Courtesy of the Seabees” sign was displayed on a beachhead.

Consolidation and improvement operations continued until October 1950, by which time the preliminary work was done and the Base Development phase commenced. In just three short weeks the Seabees had built a pontoon cause way, installed a tent city, worked on making a railway functional, and provided entertainment for the troops! All because Seabees Can Do!
