Due to the cost associated with training ammunition, training stocks require intensive management
at all levels in order to obtain the greatest training benefit at the least cost. The Army training goal is a
combat ready force prepared to mobilize and deploy on short notice, to fight and defeat the enemy, and
to increase combat readiness by providing greater, more effective training opportunities commensurate
with the missions of individual units.
COMPUTING PREPOSITIONED WAR RESERVE MATERIAL STOCKS
Requirements for computing PWRMS are determined using the traditional formula--weapons
density (WD) times expenditure rate (ER) times days of supply (DOS) equals PWRMS. (WD x ER x
The PWRMS formula data sources are weapons density, expenditures rates, days of supply, and
interpreting nonnuclear ammunition supply rates.
Weapons density includes only those weapons authorized by TOE/TDA (tables of organization and
equipment/tables of distribution and allowances) or other authorized documents, and weapons
prepositioned in a theater for mobilization forces. It does not include depot stocks, reserve weapons,
and weapons on hand at maintenance shops used as float items. For WD computation purposes, see
Appendix A, TOE 87000J440 (Mechanized Division, Heavy).
Expenditure rates are contained only in Supply Bulletin (SB) 38-26(C), Nonnuclear Ammunition
Supply Rates (U). Since this SB is classified, Appendix B was designed to present unclassified
instructions on the use of SB 38-26 and is intended for training use only. Appendix B, Nonnuclear
Ammunition Supply Rates, is organized the same way as the SB; however, it contains no classified
Days of Supply
Days of supply information for each active and anticipated theater is contained in AR 11-11(S). For
computation purposes in this subcourse any required days of supply will be provided.
Interpreting Nonnuclear Ammunition Supply Rates
Nonnuclear ammunition supply rates (expenditure rates) are broken down into four major columns
Weapon or weapon system. This column identifies the weapon or weapon system that fires the
Unit per weapon per day. This column is broken down into three separate parts and represents the
total authorization regardless of type. All USAREUR units located in US Army Europe, all
USARPAC units located in US Army Pacific, and all other units in an active theater other than
USAREUR or USARPAC (i.e., Panama) will use quantities under this column.
