COMPUTE AUTHORIZED LEVELS OF AMMUNITION
REQUIREMENT CATEGORIES
Ammunition requirements (authorized levels) are computed for ammunition storage and issue
facilities to provide a basis for evaluation of the ammunition stockpile, stratification of assets, and
redistribution of ammunition to balance assets against requirements. Ammunition assets are stocked
against four basic requirement categories: prepositioned war reserve material stocks (PWRMS),
operational project stocks, unit basic loads (UBLs), and training stocks.
Prepositioned War Reserve Material Stocks
PWRMS represent that part of the theater's war reserve of mission essential items to support post
D-Day combat consumption until resupply from Continental United States (CONUS) facilities can be
accomplished. These are stocks that are acquired and stockpiled in the active theater during
peacetime to meet increased military needs at the outbreak of war. The quantities are based on
presumed needs for a predetermined period of time.
Operational Project Stocks
Operational project stocks are that part of the theater's war reserve approved in accordance with
AR 710-1 for specific operational projects. Major commanders use this authorization to acquire
ammunition to support specific operations, contingencies, etc. There are two types of operational
project stocks: nonadditive and additive.
Nonadditive Operational Project Stocks. Nonadditive stocks are prepositioned materials to
equip or reequip specific units upon initial deployment to the active theater. These stocks are not
destined for use by on-the-ground forces, however; the stocks are preconfigured to support the
deployment of a mobilization element that has been identified to be shipped to the theater after
hostilities have begun. These stocks apply to active and reserve Time-Phased Force Deployment Data
(TPFDD) units. Since these stocks are earmarked and designated for US forces, the authorized
acquisition objective (AAO) is not normally increased.
Additive Operational Project Stocks. Additive stocks represent a stockpile contingency
assembled to meet foreseen and unforeseen requirements of allied countries in the event of war.
Control and ownership of these stocks remain our responsibility until they are transferred under the
Foreign Assistance and International Security Assistance Acts. Since these stocks are not designated
for US forces, they are coordinated and released at the Department of Army (DA) level and require an
increase to the AAO (congressional approval). Some examples of additive operational project stocks
are ammunition and explosives used to supplement war reserve deficits of Allied forces and
ammunition for insurgents. The reason for the establishment of operational projects is to set aside,
contingencies or purposes. The contingencies are normally special
