In addition to the MCTFS data, Deployment Staffing Reports (DSRs) are used to facilitate proper assignment of deployable Marines. DSRs are addressed in detail via message traffic to deploying units possessing a dedicated MCC. A year prior to the scheduled deployment, HQMC (MMEA) issues an implementation message. This message explains the DSRs, establishes staffing targets, sets "lock-on," identifies predicted entry-level school graduate arrivals, and directs submission of a monthly DSR to HQMC (MMEA-12). This report establishes a dialogue that ensures staffing of the unit by lock-on, a date when a unit has received full staffing with deployable Marines. Synchronized unit cohesion units receive staffing of their deployable Marines on a varied schedule (between 8–12 months prior to deployment) based on their fill window.
