On Tuesday the military officially ended the "don't ask don't tell" policy, which banned gays and lesbians from serving openly in the military. Gays and lesbians can no longer be thrown out of the Armed Forces because of their sexuality.
Those changes took effect at military bases across the country, including the Dover Air Force Base.
Military officials said they expect no problems as the changes take effect.
According to Secretary of Defense Leon Panetta, "These are men and women who put their lives on the line in defense of this country and that's what should matter most."
As part of the policy change, gays and lesbians who were forced to leave the military because of their sexual orientation will be allowed to re-enlist.
And military officials across the country have been trained to help usher in the change.
Delaware Senator Chris Coons was one of the sponsors of the act to repeal "Don't ask, Don't tell".
