Though later modified, the effort marked the beginning of the first Base Realignment and Closure (BRAC) process, which was intended to insulate base closings from considerations such as favoritism or other political interference. After analyzing the Secretary's recommendations, the commission may accept, reject, or modify the list. Upon completing its review, the commission forwards its final findings and recommendations to the President. The hallmarks of this framework include
establishment of an independent commission whose members are appointed by the President, in consultation with congressional leadership (and the advice and consent of the Senate); reliance on objective and uniform criteria for evaluating basing recommendations; GAO review and certification of DOD data; deliberations that include open hearings, solicitation of feedback, installation visits, and data available for public review; requirement that the commission's final list of closure and realignment actions be accepted or rejected in its entirety; and presidential and congressional off-ramps that would terminate the BRAC process when certain conditions are not met. Key milestones of a typical BRAC timeline include
DOD force structure plan, infrastructure inventory, and analysis of options (up to four years); nomination and confirmation of BRAC commissioners; DOD submission of BRAC recommendations (and associated reports) to the commission; commission deliberations (typically four months); final report sent to the President for approval; 45-day deadline for Congress to reject recommendations in their entirety (Joint Resolution of Disapproval) or allow implementation to begin; DOD implementation (two years to begin; six years to complete); and DOD disposal of real property (indeterminate). No BRAC round has established cost savings targets, floors, or ceilings. During BRAC rounds in 1991, 1993, and 1995, Congress required the Secretary of Defense to develop and report a set of objective selection criteria that would be used for identifying bases for closure and realignment. For the 2005 round, Congress amended the BRAC statute to require the Secretary to regard military value (defined below) as the primary consideration. BRAC Legislation in the 115th Congress

In 2017, Members in both chambers proposed legislation that would have authorized a new round of base closures. 2687, the first statutory restriction on the President's ability to close or realign military installations. (2) Acceptance of recommendation.—If the Secretary of Defense determines that it is in the interests of the United States to accept the recommendation for the realignment or closure of a military installation which is the subject of a notice received under subsection (b) and intends to carry out the realignment or closure of the installation pursuant to the authority of this section during a fiscal year, at the time the budget is submitted under section 1105(a) of title 31, United States Code, for the fiscal year, the Secretary shall submit a report to the congressional defense committees which includes the following:
(A) The identification of each military installation for which the Secretary intends to carry out a realignment or closure pursuant to the authority of this section during the fiscal year, together with the reasons the Secretary of Defense believes that it is in the interest of the United States to accept the recommendation of the Governor of the State involved for the realignment or closure of the installation.
Since 1977, statutory thresholds have effectively constrained the President's ability to close or realign major military installations in the United States. Congress has instead periodically granted temporary authorities—known as a Base Realignment and Closure (BRAC)—that have established independent commissions for the review and approval of basing changes submitted by the Secretary of Defense. These unique and transient authorities last expired on April 16, 2006. There have been five rounds of base closures: 1988, 1991, 1993, 1995, and 2005.
Though Congress has periodically adjusted the BRAC process to account for lessons learned, the modern framework has remained generally consistent with earlier rounds, and includes
establishment of an independent commission; reliance on objective and uniform criteria; Government Accountability Office (GAO) review and certification of Department of Defense (DOD) data; deliberations designed to be transparent that include open hearings, solicitation of feedback, installation visits, and data available for public review; and requirement that the final list of closure and realignment recommendations be accepted or rejected in their entirety.
Congress has defined BRAC selection criteria in statute, thus requiring the Secretary to prioritize military value over cost savings. Additionally, Congress has required the Secretary to align the Department's recommendations with a comprehensive 20-year force structure plan. The commission may modify, reject, or add recommendations during its review before forwarding a final list to the President.
After receiving the Commission's list of recommendations, the President may either accept the report in its entirety or seek to modify it by indicating disapproval and returning it to the commission for further evaluation. If the President accepts the commission's recommendations, they are forwarded to Congress. BRAC implementation begins by default unless Congress rejects the recommendations in their entirety within 45 days by enacting a joint resolution. During the implementation phase, DOD is required to initiate closures and realignments within two years and complete all actions within six years.
The BRAC process represents a legislative compromise between the executive and legislative branches wherein each shares power in managing the closure and realignment of military bases. The imposition of an independent, third-party mediator was intended to insulate base closings from political considerations by both branches that had complicated similar actions in the past.
This report provides background on the development of BRAC, describes its major elements and milestones, and outlines issues frequently cited in the context of new rounds, such as potential savings.
