PERFORMANCE EVALUATION SYSTEM 20102-7 2. Non-Marine Reporting Officials. Definitions, roles, and responsibilities of the RS and RO are applicable to officers of other branches of the armed services, officers of foreign nations, and civilians in positions of authority under whom the MRO may serve. Civilian RS authority starts with GS-9/equivalent (see paragraphs 2003.1 and 6008). 3. Multiple and Simultaneous Regular Duty Assignments. Occasionally, operational necessity will require assigning Marines to more than one primary duty, with each having its own operational (reporting) chain. When applicable, submit separate reports via each reporting chain. Example: MRO is a regimental commander also serving as camp commander. The regimental commander receives reports from both division and base commanding generals. Another example: MRO belongs to a non-Marine command but as a result of a letter of instruction (LOI) or similar document, has specific Marine Corps responsibilities to the senior Marine officer present. The latter may submit a simultaneous report addressing Marine Corps matters only. These are separate and distinct report occasions per paragraph 3003.3 as applicable. Forward each report for review through the appropriate reporting chain. NOTE: Begin section I with the following statement: "Simultaneous report". The RS will then explain the circumstances, which warranted a simultaneous report. 4. Seniority Issues. The following rules apply: a. The RS will never be junior in grade to the MRO. b. In situations where the MRO is the same grade as the RS, elevate the reporting chain one level to the next senior officer or civilian equivalent supervisor. NOTE: The only exceptions to this policy are when the RS is the commanding officer or officer in charge, when the RS is frocked to the next senior grade but holds the same permanent grade, and when the RO authorizes a staff officer of equivalent grade to the MRO to function as the RS by so indicating the authorization in section K (see paragraph 2004.3). c. The same seniority relationships apply between the RS and the RO. When the RO is the same grade as the RS, comments in section K must indicate the authority source.
