A Joint Base Elmendorf-Richardson airman was demoted and received a letter of reprimand for peeing in his squadron’s office coffee maker, among other violations of the Uniformed Code of Military Justice, according to documents from the base.

Formally charged as a violation of Article 92, dereliction of duty, the unnamed airman “knew or should have known” to “refrain from urinating in the squadron coffee maker,” according to the redacted charge sheet provided by the base public affairs office. The incident occurred sometime between Jan. 1 and Oct. 31, 2019, but the document does not stipulate how the crime was discovered.

The airman also faced a charge of being absent without leave from Nov. 27 until he was apprehended on Dec. 2. Both charges were addressed through Article 15, which allows the commander to determine guilt and punishment for minor offenses instead of through a judicial hearing.

The airman received the letter of reprimand as well as a demotion in rank to airman basic, the Air Force’s lowest enlisted rank.
