General Clarke said the review, which will conclude this fall, will seek insights from leaders inside and outside the Special Operations ranks. He said the review will also focus on recruitment, grooming leaders and education and training, and how “to address ethical failures when they occur.”

Exactly what will emerge from the review is unclear. This year, the Pentagon completed a congressionally mandated study of Special Operations ethics and cultures. But lawmakers complained it rendered few hard-hitting changes. One result was that General Clarke’s predecessor directed a 90-day “focus period” on core values.

Indeed, the problems plaguing commandos have persisted. A week after the platoon was pulled from Iraq, the leader of the Navy’s Special Operations forces, Rear Adm. Collin P. Green, told his command in a strongly worded letter that “we have a problem” with breakdowns in discipline among members of the Navy SEALs “that must be addressed immediately.”

The withdrawal of the platoon was the latest in a series of black eyes for the SEAL teams.

Two members of the SEALs and two Marines were charged in the death of a Green Beret who was strangled in 2017 during a hazing incident while the commandos were on a secret deployment in Mali, in West Africa. One of the SEALs commandos pleaded guilty and was sentenced in May.

Navy Times reported last month that cocaine use was widespread on SEAL Team 10, based in Virginia, and that members of the team considered the Navy’s drug testing efforts “a joke.”
