A group of 56 retired generals and admirals have signed a letter in opposition to Trump's transgender military service ban, arguing that it would undermine readiness.
When Trump first announced the ban I opined that it would be an even worse version of Don't Ask Don't Tell and these former leaders apparently agree.
You can read their full letter here:
This proposed ban, if implemented, would cause significant disruptions, deprive the military of mission-critical talent, and compromise the integrity of transgender troops who would be forced to live a lie, as well as non-transgender peers who would be forced to choose between reporting their comrades or disobeying policy. As a result, the proposed ban would degrade readiness even more than the failed ‘don't ask, don't tell’ policy. Patriotic transgender Americans who are serving—and who want to serve—must not be dismissed, deprived of medically necessary health care, or forced to compromise their integrity or hide their identity.
When Trump announced his ban, he said he consulted "my generals"...
After consultation with my Generals and military experts, please be advised that the United States Government will not accept or allow......

...but there don't appear to be any actual generals who support Trump's decision. These retired generals and admirals don't and the Joint Chiefs of Staff have made it clear that they will not change their policy just because Trump tweeted it.
