One of the functions of the WWII era Marine Corps military service record was to document the battle participation of individual Marine Corps veterans. While there may be a number of documents within the military service record of your veteran which highlight or point to combat experiences, the military service record booklet is the place where the veteran’s engagements and expeditions are officially listed. The military service record booklet is a small booklet that is kept inside of your veteran’s official military service record (along with a great deal of other documents pertaining to his military service history). As your veteran’s military career progressed, a chronological record of his expeditions, engagements and battle participation would have been maintained within the service record booklet as a way to document his combat experiences and overseas service. This would ensure that the veteran received the credit- and the appropriate medals/ribbons to signify his participation in major campaigns and battles. It would also have provide superior officers with an overview of the experiences of the men under their command and allowed them to place enlisted men in positions where their experiences and skills might be put to the best use. The ‘Engagements and Expeditions’ section of the military service record booklet was constantly being updated as the veteran moved from station to station or participated in a new combat mission. In most cases a short description of the veteran’s battle or expedition participation was typed up by the unit clerk and then this descriptive strip of paper was either glued or stapled into the service record booklet (usually right on top of the previous engagement strip). This would have been done after each battle had concluded, rather than being compiled all at once at the conclusion of your veteran’s service.
Obviously, archival preservation was not really a priority for WWII Marine Corps unit clerks or higher headquarters and this makes copying and viewing the ‘Engagements and Expeditions’ section of the WWII Marine Corps military service record something of a chore. Because these strips are often glued into the Marine Corps service booklet, they have to be painstakingly photocopied to prevent damage. When the expedition and battle participation strips are stapled into the Marine Corps service record booklet, they can often be gently removed from the booklet, copied, and then placed back into the military service record for safe keeping. If you are seeking to find out where your veteran was and the battles that he participated in, the ‘Engagements and Expeditions’ section of the Marine Corps military service record booklet is the place to begin your journey.
