The first openly transgender recruit joins the US military

The first openly transgender person has signed up to join the U.S. Armed Forces.

On Feb. 27, the Pentagon confirmed that the recruit signed a contract to join the military after a federal judge ruled that transgender individuals who meet the standards for military service must be allowed to join.

Here is a brief timeline of recent events concerning transgender military eligibility: 

• June 30, 2016: Defense Secretary Ashton Carter announced that the U.S. was lifting the ban on transgender people serving in the military.

• June 30, 2016: A RAND study determined medical care for individuals who transition would cost roughly $2.4 to $4 million annually, thus amounting to no more than 0.13% of spending on healthcare for active duty armed service members.

• July 26, 2017: President Donald Trumped announced on Twitter that transgender individuals would no longer be allowed to serve "in any capacity in the U.S. Military."

• Aug. 29, 2017: Secretary of Defense James Mattis announced that currently serving transgender troops would be allowed to remain in the armed services, pending the recommendations of a panel study and consultation with Homeland Security.

• Jan. 1, 2018: Transgender individuals were allowed to join the U.S. military after the Pentagon was forced to comply with a federal court ruling issued in December 2017.

• February 23, 2018: The Pentagon confirmed that there is one transgender individual under contract for service in the U.S. Military.

Under the guidelines effective Jan. 1, 2018, transgender applicants must be certified by a medical provider as stable without "clinically significant distress or impairment in social, occupational, or other important areas of functioning" for 18 months in order to be eligible to serve.

Secretary Mattis maintains that "our focus must always be on what is best for the military's combat effectiveness leading to victory on the battlefield."
