WASHINGTON — The Army has issued a new reprimand to the leader of the Green Beret team that was ambushed in 2017 in Niger.

Capt. Michael Perozeni was cited in a letter dated Jan. 16 for not performing proper pre-mission training before the mission that led to the ambush, according to military officials.

The reprimand, issued by Lt. Gen. Francis M. Beaudette, the head of the Army’s Special Operations Command, will go into Captain Perozeni’s “local” personnel file, meaning it should not follow him throughout his military career.

Four American soldiers and five Nigerien troops were killed in the Oct. 4, 2017, ambush while searching for a militant linked to the Islamic State.
