War Reserve Secondary Items

What is it?
War Reserve Secondary Items (WRSI) are the wartime sustainment element of the Army Prepositioned Stock (APS) program. WRSI consist of secondary items that sustain the battle by replacing supplies consumed in combat operations. Classes of WRSI supportive of contingency and wartime operations include I, subsistence items; II, clothing and textiles; III packaged material (oil and lubricants); IV, construction and barrier material; VIII, medical supplies; and IX, repair parts and major assemblies. Specific aggregates of WRSI, including the Authorized Stockage List (ASL), Prescribed Load List, and Unit Basic Load (UBL), may be deployed, ashore or afloat, in support of heavy brigade combat teams (HBCTs), infantry brigade combat teams (IBCTs), fires brigades, and sustainment support brigades (SSBs). Class VIII ASLs and UBLs of WRSI can be provided to corps and higher echelons, combat support hospitals, minimal care detachments, early-entry hospitals, and forward surgical teams in strategic APS locations ashore and afloat.

What has the Army done?
During Operation Iraqi Freedom (OIF, Iraq) and Operation Enduring Freedom (OEF, Afghanistan), the Army issued WRSI stocks it had prepositioned both afloat and ashore. The Army learned many lessons during OIF concerning what to stock and how to support WRSI requirements. The Army is now in the process of a holistic review of the WRSI program, to include examining how we determine requirements as well as how we support those requirements (stock forward or leverage existing assets of the Defense Logistics Agency [DLA] and Army Materiel Command [AMC]). In the past, WRSI requirements were determined by a model that OIF historical data suggest was flawed. The current analysis will use the actual OIF and OEF demand histories to establish more-effective starter stocks for a deployed force. The review also entails examining whether it makes fiscal and operational sense to purchase and store all the items forward instead of using the existing DLA and AMC infrastructure.

What continued efforts does the Army have planned for the future?
The Army senior leadership approved the new APS Strategy 2015 in November 2007. When that strategy is fully implemented, modular land-based HBCTs will be combined with modular IBCTs afloat at strategic locations worldwide. The combined teams will be provided with essential unit sets of combat support/combat service support WRSI, to include medical supplies and watercraft to support deployment into austere environments. In support of the APS 2015 Strategy, the Army will continue to refine WRSI requirements, in part by ensuring that the requirements of combatant commanders are based on actual demand and in part by continually updating and refreshing WRSI stocks. The Army will also continue to leverage the existing capabilities of the DLA and the AMC to provide more responsive support to the deployed force.

Why is this important to the Army?
Units deploy with their basic sustainment load of all classes of equipment. Once in an area of operations, they begin to use that basic load and order replenishment stocks. Wartime demands are inherently greater than peacetime demands, and there is usually a lag between the build-up of stocks and the movement thereof into an area of operations to support a deployed force. WRSI provide the link between a unit’s basic land sustainment loads by providing starter stocks to support the deployed force until communication and resupply lines from the continental United States can be established. A fully funded and supported WRSI stock is essential to ensuring uninterrupted sustainment of a deployed force.
