Enforcing the ban on open gay service cost the military nearly $200 million over six years, according to a new report from the Government Accountability Office, the Stars and Stripes reported.

The policy, known as “Don't Ask, Don't Tell,” was effectively repealed during Congress' lame-duck session in December but won't be officially lifted until after President Obama and Pentagon leaders certify that the military is ready for the change.

From fiscal 2004 through fiscal 2009 the military spent roughly $53,000 per gay service member dismissed under the policy. The majority of the expense, according to the report, came from costs associated with recruiting replacements and retraining of new troops.

The report also estimates administration costs at $8 million. That includes legal work, processing of separation paperwork and addressing inquiries.

The report was compiled at the request of Congressional Democrats.

On Wednesday, California Representative Duncan D. Hunter, a Republican, introduced legislation that if approved would almost certainly block repeal of “Don't Ask, Don't Tell” by requiring the four service chiefs to sign off on repeal of the policy.
