Two key unions are opposing an amendment to the fiscal 2018 National Defense Authorization Act in the Senate that would authorize a new round of military base realignments and closures.

Senate Armed Services Chairman John McCain (R-Ariz.) and ranking Democrat Jack Reed of Rhode Island are pushing an amendment to the NDAA H.R. 2810 (115) to authorize a new BRAC round. But in separate letters, the American Federation of Government Employees and the International Association of Machinists and Aerospace Workers blasted the BRAC process, specifically questioning predictions of savings that would result.

“In this age of military uncertainty, it is not the time to authorize a new BRAC round,” the AFGE letter (attached) argued. “A new round of BRAC would incur significant upfront costs at a time of significant fiscal restraint under the Budget Control Act.”

The IAMAW letter (attached) argued that, by capping implementation costs, McCain and Reed’s BRAC proposal would leave “highly distressed communities and working families without the vital assistance needed to recover from a government imposed economic disaster.”

The Pentagon has requested the authority to close and consolidate infrastructure, arguing the process could save upwards of $2 billion a year.
