[58] This account of the build-up of the 7th Marines is based on the summary in PacFlt Interim Rpt No. 1, XV: Zebra, pt. V.
Colonel Homer L. Litzenberg was designated as commanding officer on the date of activation, 17 August 1950. The Chief of Naval Operations directed the regiment to embark for the Far East not later than 3 September. These components were included in the build-up:
3d Battalion, 11th Marines; Company D, 1st Tank Battalion; Company D, 1st Engineer Battalion; Company C, 1st Shore Party Battalion (including two Shore Party communication teams from Signal Company, Signal Battalion); Company D, 1st Motor Transport Battalion; Company E, 1st Medical Battalion.
Forming the nucleus of the regiment, the 6th Marines, at peace strength and less two battalions, arrived from Camp Lejeune on 16 August. The 3d Battalion of this FMFLant regiment, then stationed afloat in the Mediterranean, was ordered to proceed through the Suez Canal to become part of the 7th Marines upon arrival in Japan.
While the other elements were being absorbed at Camp Pendleton, a conference attended by General Smith, Major General Alfred H. Noble, and Colonel Litzenberg was held to discuss rear echelon personnel and the formation of RCT-7. The following troops were found to be available to take care of casuals and retain custody of such division supplies and equipment as had not yet been embarked:
| MARINE CORPS | NAVY | ||
| Off. | Enl. | Off. | Enl. |
| 224 | 1,029 | 11 | 35 |
Not included in these figures were 197 noneffective enlisted personnel, a rocket battery, a motor transport company, and the organizational rear echelon of eight officers and 28 men. It was decided that General Noble, as FMFPac representative, would examine MOSs, to determine how many men would be transferred to the 7th Marines or retained for FMF units to be activated later. The need was also foreseen for rear echelon working parties to relieve personnel of units mounting out.[59]
