COMPUTING REQUIRED SUPPLY RATE
The required supply rate (RSR) is the amount of ammunition expressed in rounds per weapon per
day estimated to be required to sustain operations of any designated force, without restrictions for a
specified period of time. RSRs are submitted by tactical units in the TO. RSRs are consolidated at
each command level, brigade, division, corps, etc., until they reach the theater ammunition managers
who determine whether RSR can be supported.
Basic data used as a guide in computing the RSR is contained in Appendix D, Ammunition in
Rounds Per Weapon Per Day and STONs Per Day by Level of Operation for All Types of Divisions.
To compute levels of operation use Figure 3.
The defense of position and attack of position are both divided into the two time periods, first day
and succeeding days. The first day time period represents the first 24-hour period of engagement. The
succeeding days' time period represents the second, third, and fourth day of the battle.
