The possibilities seem endless for Sierra Davis. At the age of 23, she has a lot of ideas about what her future can hold. But just a couple years ago, she was in the infantry.

Davis was 17 when she enlisted in the Marines.

At that time, transgender people were not allowed to serve openly, but Davis had not transitioned into Sierra yet.

But who she is today would be accepted under a new policy by the Pentagon.Transgender people will be allowed to enlist in the military beginning Jan. 1 2018.

"I feel like most other people in the country are starting to be like, wait that's dehumanizing. That's not right. People are people and if they want to fight for the country, we should let them fight for the country," Davis said.

A federal judge on Monday denied the Trump administration's request to delay an order requiring the military to begin accepting transgender recruits, saying the argument for more time seemed based on "vague claims."

President Trump sent out a series of tweets in July about banning transgender individuals from the military.

"It's extremely offensive to have the commander-in-chief of those service members say you're not human enough to serve with my other service members," Davis said.

Davis is relieved about the new policy but warns there is still a lot to figure out.

"It's opening a door and everyone rushing in not knowing what's behind that door," Davis said.

Potential transgender military recruits will have to overcome a lengthy and strict set of physical, medical and mental conditions that could make it difficult for them to join the armed services.

The Pentagon also stated that transgender individuals receiving hormone therapy must be stable on their medication for 18 months in order to enlist.

The Trump Administration is considering other legal options concerning the ruling.
