Disobedience of the orders of any officer or noncommissioned officer. 3. Disrespect to an officer or noncommissioned officer. 4. Absence from camp without leave. 5.

In the interpretation of the regulations the spirit must be sought. Quibbling over the minutiæ of form is indicative of failure to grasp the spirit."
