An estimated 400,000 former service members are at risk of wrongly being denied VA health care and other benefits, according to a 2020 study by OutVets, a group of LGBTQ+ military veterans.

So are veterans who served in the Navy or Marines, the wars in Iraq and Afghanistan, and those with post-traumatic stress disorder.
