The White House has finally issued guidelines for the transgender military ban — sending a 2½-page memo to the Pentagon directing Defense Secretary Jim Mattis to enact the rules within six months.

Officials familiar with the document told the Wall Street Journal that the regulations will ultimately allow Mattis to consider a service member’s ability to deploy when deciding whether to give them the boot.

They will also give the Pentagon the power to deny admittance to transgender military members — and to halt spending on medical treatment for those currently serving, the sources said.

When weighing one’s “deployability,” Mattis reportedly will be looking at their ability to not only serve in a war zone, but also whether they can participate in exercises or live for months on a ship.
