After a 20-year career with the Navy Seals, Chris Beck has revealed her true identity as a transgender woman named Kristin Beck, ABC News reported.

Transgender men and women are still not permitted to serve in the U.S Armed forces. Kristin began her transition after retiring from the military in 2011 and has now published a memoir titled "Warrior Princess: A U.S. Navy SEAL's Journey to Coming out Transgender," available on Amazon.com.

Beck enlisted as a petty officer in the Navy Seals and received a Bronze Star and a Purple Heart, as well as seven warzone deployments. She even went a tour in Seal Team Six, the unit responsible for the hunting and killing of Osama Bin Laden.

Raised Chris, Beck never felt comfortable as a man and a fellow Navy Seal said in a blog post that he noticed Chris was different.

"While Chris was always a little different I had no idea what was lying under the surface, as I'm sure a lot of people will have the same experience," he said.

Since revealing her true identity, Beck has received support from admirers, former Seals, the National Gay and Lesbian Taskforce (NGLT) and the National Center for Transgender Equality (NCTE).

Her revelation comes almost three years after the Department of Defense lifted its ban on openly gay and lesbian men and women serving in the military. Now the NCTE wants the ban on transgender men and women to be lifted.

"Not only is this unjust to individual transgender people who wish to serve their country through military service, it weakens our national defense by barring qualified people from duty," the NCTE states on their website.

To complete her transition, she shaved her thick beard and began wearing women's clothes and posted a picture on her LinkedIn page with the statement: "I am now taking off all my disguises and letting the world know my true identity as a woman."

According to a report by the Atlantic Wire, Beck received encouragement from fellow Seals.

"Brother, I am with you ... being a SEAL is hard, this looks harder. Peace," one wrote

"I can't say I understand the decision but I respect the courage. Peace and happiness be upon you," another wrote.

The journey continues for Beck, but she continues to receive support even if her peers do not understand.

As she wrote on her Twitter account recently, "[I am] now working toward my own peace as a woman."
