Operation and Support Cost Reduction (OSCR) The U. S. Army spends a large part of its overall budget, directly or indirectly, on the operation and support (O&S) of equipment ranging from small generators to large, sophisticated weapon systems. O&S costs cover a broad spectrum of items including spare/repair parts, fuels, lubricants, and the facilities and people involved in training operators and mechanics. The Army is seeking ways to reduce these costs as a broad Acquisition Reform initiative. To this end, the Army has implemented the Operation and Support Cost Reduction (OSCR) Program. This solicitation includes 89 topics that address specific OSCR concerns identified by the Army’s research and development community.
