The Pentagon discharged 250 service members last year for violating “Don't Ask, Don't Tell,” the law that bans gay and bisexual troops from serving openly.

The figure covers the period between October 1, 2009 and September 30, 2010.

Aubrey Sarvis, executive director of Servicemembers Legal Defense Network (SLDN), the largest group lobbying for the law's repeal, said the all-time annual low serves as a reminder that the policy remains in effect.

“While even one discharge under the discriminatory 'Don't Ask, Don't Tell' law is too many, the 2010 numbers represent a marked decline from years before,” Sarvis said in a statement.

In December, Congress approved and President Barack Obama signed into law a bill that repeals the Clinton-era law. But implementation won't begin until 60 days after Pentagon leaders and the president certify that the military is ready for the change.

Sarvis used the new figures to push for an earlier than expected end to the policy: “But these numbers underscore the need to accelerate the timeline for training and repeal.”

“The reality is that investigations continue and service members are still in danger of being discharged,” Sarvis added. “We look forward to certification by Secretary Gates, Chairman Mullen, and the President as we move toward full repeal. Until we achieve full equality for all LGBT service members, the job is not done.”
