Article 91 of the Uniform Code of Military Justice (UCMJ) addresses failures related to proper equipment under the context of "insubordinate conduct" and "disobedience of lawful orders." While it does not specifically mention equipment failure directly, it can be applied to situations where a service member fails to comply with orders regarding the maintenance or use of equipment. Additionally, Article 92 covers failure to obey orders or regulations, which can also pertain to the proper handling and maintenance of military equipment.
Generally such a charge is prosecuted under Article 92, UCMJ, as an orders violation. Each service has an order regarding relationships among the ranks.
