Generally, military law is similar to civilian law regarding blood alcohol content (BAC) levels. Regarding DUI, drunk on duty, and other alcohol-related offenses, an individual cannot have a BAC of over 0.08% or be too incapacitated to perform their duties. While 0.08% is more of a baseline for determining incapacitation, a service member can have a lower level and still be found guilty of being drunk on duty.
