What does the RMC primarily do with service treatment records (STRs)?

The primary function of the RMC (Records Management Center) concerning service treatment records (STRs) involves the maintenance of these records for veterans who do not have claims folders. The RMC ensures that STRs are preserved and accessible, allowing for accurate information retrieval that can aid in delivering appropriate benefits and services to veterans.

Maintaining STRs is crucial for the continuity of care and processing claims, especially for veterans who may not have accompanying claims folders. This task contributes directly to the overall mission of supporting veterans by ensuring that their medical histories are documented and available when needed.

The other options pertain to different processes or responsibilities that do not align with the RMC's primary duties regarding STRs. For instance, transferring STRs to the Department of Defense or managing the National Archives encompasses broader responsibilities that fall outside the daily operations of the RMC concerning the maintenance and accessibility of service treatment records for individual veterans.
