Although gays in this country cant currently marry, in June of this year the Obama administration directed the Office of Personnel Management to provide these benefits to same sex domestic partners within the federal government:

Additionally, the administration provides a means for same sex domestic partners to form a civil union in the eyes of the federal government:

It follows that gays on active duty will be able to establish faux spouses who will receive all the benefits real military spouses receive.
These benefits include commissary/PX privileges, special job consideration for civil service appointments, base family housing assignments, moving expenses, active duty survivors benefits, retirement survivors benefits and probably a number I havent thought of.
My concern is that these benefits are paid for by taxpayers who morally object to this policy.
