required supply rate (ammunition)

The amount of ammunition expressed in terms of rounds per weapon per day for ammunition items fired by weapons (and in terms of other units of measure per day for bulk allotment and other items) estimated to be required to sustain operations of any designated force without restriction for a specified period. Tactical commanders use this rate to state their requirements for ammunition to support planned tactical operations at specified intervals. The required supply rate is submitted through command channels. It is consolidated at each echelon and is considered by each commander in subsequently determining the controlled supply rate within the command. Also called RSR. See also ammunition controlled supply rate.
