1942…First female CEC Officer-Ensign Kathleen F. Lux

1967…NMCB-7 completed the second increment of Camp Tien Sha Barracks rehabilitation.
…While deployed to Phu bai, NMCB-121 constructed numerous buildings which were covered with corrugated metal roofing. Installation of the metal roofing was a slow and costly process because there was no efficient method to put starting holes in the metal roofing
In the field men had to use nails, center punches, electric drills (which required generators) or any means available to make the pilot holes in the metal. All of these methods caused damage to the material, additional tools, bodily injury, and were time consuming.
To make installation of metal roofing more efficient, a standard claw hammer was modified. A hole was drilled in the side of the head and tapped with a ¼”-20 N.C. Tap. A ¼”-20 N.C. Stud (Ramset) was screwed into the tapped hole and locked with a ¼” hex nut. By using this hammer and ramset stud as a punching device, the roofing maetal could be installed with much increased efficiency
…NMCB-121 installed 60,000 square yards of M8A1 matting for use as a helicopter pad. A tremendous amount of man-hours would have been required to close all pin connections if done by hand. Alpha Company mounted an air hammer on wheels which permitted driving the four pins in each sheet in a total of ten seconds.
…CBMU-301 was tasked with the maintenance of the approximately twenty miles of road at the Dong Ha Combat Base. All roads were unpaved laterite. The primary problems associated with the Combat Base road system were traffic being very heavy including tracked vehicles such as tanks, amtracs and LVT’s. Also, a combination of heavy rains during the monsoon season and inadequate drainage caused ruts, pot holes, and general surface deterioration.
During the monsoon season, maximum use was made of the lull in the rains to construct much needed culverts. During the dry season, dust control was a major problem. The dust suppression program was primarily one of spraying the roads with an asphalt-diesel fuel mixture. The spraying was done at night when the traffic was relatively light, thus allowing the asphalt/diesel oil mixture a longer time to soak in and cure

1968… NMCB-22 hosted a Thanksgiving party for Vietnamese children
… General Walt Scholarships for needy and deserving students were made available through the G-5 at First Marine Division. During the deployment the NMCB-1 assisted ten students at Bo De School with these scholarships. Each scholarship consisted of 500 piasters per month for one school year. During the deployment several men of the battalion chose to assist an additional 25 students at Bo De School with a one year scholship in honor of LTJG D.A. Moscrip Jr. which cost $25.00 per donor. A very rewarding event for both the sponsors and students was the inviting of these scholarship students to have Thanksgiving Dinner with their sposnsors at Camp Hoover. The galley personnel did an outstanding job in making this event a success.
…RADM W.M. Heaman, CEC, USN, COMCBPAC and RADM J.V. Bartlett, CEC, USN, COM3NCB, visited NMCB-133 at Camp Campbell, Phu Bai.
…NMCB-121 observed Thanksgiving with a religious service and a two hour lunch period.
…NMCB-7 celebrated Thanksgiving Day with a half day work routine and a superbly prepared meal in the EM Galley.
…RADM W.M. Heaman, COMCBPAC and RADM J.A. Bartlett, COM3NCB, visited NMCB-7 at Camp Barnes for the Battalion Color and Awards Ceremony. Sierra Company was honored as the new Color Company, and HM3 J.E. Bradley was awarded a Bronze Star. Also present were Commodore A.W. Walton, COM32NCR and CAPT H.F. Curren, Inspector General, NAVFACENGCOM
…At 1910 a hand illumination flare started a fire in the 3NCB storage yard. The fire was contained by 1940 bt the NMCB-3 Fire Fighting crew.
…Radm. W.M. Heaman, CEC, USN, COMCBPAC; Radm. J.V. Bartlett, CEC, USN, COM#RDNCB; Capt. A.W. Walton, CEC, USN, COM#@NDNCR, and Capt. H.F. Curren, CEC, USN, Inspector General NAVFAC, on board for an official visit to Bridge 13.
…NMCB-22 was assigned the task of designing the new camp at Vinh Dai some 6 miles west of Dong ha on Route 9. NMCB-7, located at Dong Ha, was given the construction responsibility for the new location.
Just 34 days after closing out the Nam Hoa operation, the first rock was crushed at Vinh Dai. NMCB-22 installed a new 200 Ton per hour rock crusher to produce crushed rock for the road base construction and the older 200 Ton per hour Nam Hoa crusher to produce asphalt and concrete aggregate.
The method of quarry operation differed radically from that at Nam Hoa. Washed river rock was obtained from the bed of the Cam Lo River at a site 10 miles to the west of the crusher site. River rock approximately 12” to 18” in diameter was pushed into piles by crawler front end loaders and hauled to the crusher site.
Unlike at Nam Hoa the hauling operation from the river to the crusher was the prime factor limiting rock production. Wear on the crushers was relatively mild because the rock crushed easy and there was larger quantities of free run through the creushers. Production at Vinh Dai was in most instances more than double that of Nam Hoa. NMCB-22 established a record of 2,829 tons produced by one crusher in a 12-hour day and 10,800 tons produced by one crusher in a single week.
The Vinh Dai detachment consisted of two officers and approximately 170 men. Some 40 men were assigned to permanent security group 7 of which were assigned to river quarry site security.
Many of the same problems were encountered at Vinh Dai as at Nam Hoa. The logistic support problem was magnified by an increased distance from Camp Haskins. Equipment parts were still difficult to obtain and a more rigid PM schedule was required with the increase of hauling equipment.
Other problems included:
A. A more serious camp defense situation existed with the nearness to the DMZ. Production was slowed or stopped upon occasions because of enemy activity at the river site as well as near the main camp. A Marine Tank Company and an Army duster unit were permitted to share the main camp site in turn for security support.
B. Probablt the most consistant deterant to good production was the problem of mine sweeping the roads to the river site. This was not accomplished until approximately 0930 to 1000 hours each morning and delayed the already critical hauling operation.
C. Having the crushing operation under the operational control of the 3rd NCB somewhat blurred the responsibility of the Battalion (NMCB-22). It was questionable whether there was any advantage to such an arrangement. It was recommended that a study be made into the possibility of assigning the operational control of the crusher facility to the Battalion. Then there was the question what the Battalion’s responsibility would be and the operation would be treated as a special project and managed similar to any other high priority assignment.
A 150 ton per hour portable asphalt plant was scheduled to be installed in mid-March 1969. NMCB-22 designed the layout and submitted it to the 32nd NCR for approval. NMCB-7 was to construct all foundations in preparation for the planr erection. NMCB-22 was relieved of the Vinh Dai operation responsibility on 03 March 1969.
…Radm W.M. Heaman, CEC, USN, Commander Naval Construction battalions, U.S. Pacific Fleet, Radm. J.V. Bartlett, CEC, USN, 3rd NCB, capt. H.P. Curren, CEC, USN, NAVFAC, and Capt. J.R. Fisher, CEC, USN, Commander 30th NCR attended a luncheon with officers of NMCB-22 and then toured major job sites including FLC, III MAF Transient facility, and TRI-ATCO Area at Da Nang Air Base.
…NMCB-12 was tasked with road maintenance of Route 13C
