Here's a background doc on it, dealing solely with officer drawdown figures (the enlisted numbers are far, far greater):

THE DOWNSIZING PLANS OF THE SERVICES
The special incentives--VSI, SSB, and TERA--were not available to the services in 1990 when they submitted their initial downsizing plans (covering the 1991-1995 period) to the Secretary of Defense. The services were therefore limited in how they could balance cuts in accessions with increased separations of officers already in the force.
The Army's and Air Force's initial plans called for reducing their officer corps by 26 percent and 20 percent, respectively (see Table 3). The Army hoped to reduce the number of officers by means of selective early retirements, the voluntary early release of officers who had not yet completed their initial period of obligated service, and some cuts in accessions. The Army had followed a similar approach when it reduced its officer corps in 1987.(12) The Air Force planned to rely heavily on the separation provisions in the promotion system and on SER boards. Although Air Force managers had relied on large cuts in accessions to reduce the number of officers in 1987, they did not plan to repeat that strategy.(13)

The Navy's and Marine Corps's initial plans called for more modest cuts in their officer corps--10 percent and 13 percent, respectively. The Navy planned to achieve its reductions using SER, cuts in accessions, and the up-or-out provisions of the promotion system. The Marine Corps planned to rely on SER and on a provision in DOPMA that allows the separation of officers holding reserve commissions.(14)
As the ultimate shape and size of the post-Cold War military gradually became clearer, the Navy and Air Force revised their plans to accommodate larger reductions. By 1995, the Navy's officer corps was about 6,000 below the level initially planned for that year, and the Air Force's officer corps was about 4,000 below the level initially planned (see Table 3 and Figure 3).
