Because of the growing threat of regional conflicts, Aspin wanted to have a strong capability to carry out limited military operations, including peacekeeping, and to maintain "a strong peacetime presence of U.S. forces around the world". The bottom-up review report, which Aspin released in September 1993, took into account strategy formulation, force structure, weapon systems modernization, and Defense infrastructure. The report projected a reduced force structure still capable of fighting and winning two simultaneous major regional conflicts. Forces would include 10 active Army divisions; 11 carrier battle groups, 45 to 55 attack submarines, and about 345 ships; 5 active Marine brigades; and 13 active and 7 reserve Air Force fighter wings. The report also called for additional prepositioned equipment and airlift/sealift capacity, improved anti-armor and precision-guided munitions, and enhanced Army National Guard combat brigade readiness.
