This bill requires the Government Accountability Office to study how well military discharge review boards are following federal requirements to give "liberal consideration" to veterans' discharge upgrade requests, particularly for those with mental health conditions, sexual assault trauma, or sexual harassment claims. The study will examine whether discharge review boards are properly implementing two key Pentagon memoranda from 2014 and 2017 that directed boards to carefully reconsider discharges under these circumstances, and will identify any barriers preventing boards from following these directives. The GAO must brief Congress on preliminary findings within 180 days of the bill's enactment and provide a full report at a later agreed-upon date. The legislation does not allocate specific funding but directs an investigation into government compliance with existing policies, affecting veterans seeking to appeal or upgrade their military discharge status.
