What is contained in a service record in the USMC?

The correct answer is the documented history of activities and accomplishments. In the United States Marine Corps, a service record serves as a comprehensive account of a Marine's entire career. It includes a wide range of information such as training, assignments, evaluations, awards, and any significant milestones achieved throughout their service. This holistic documentation aids in tracking the individual’s progress, performance, and overall contributions to the Marine Corps.

While physical fitness scores and performance evaluations are indeed part of a Marine’s record, they represent only segments of this extensive documentation. Awards and decorations, although important, also fall under the umbrella of accomplishments rather than encapsulating the whole record. Thus, the service record is a complete narrative rather than just a collection of specific achievements or documents.
