A child with AD/HD [ A.D.D. OR ADHD ] is usually described as having a short attention span and as being distractible. In actuality, distractibility and inattentiveness are not synonymous. Distractibility refers to the short attention span and the ease with which some children can be pulled off-task.
Both the U.S. Navy and the U.S. Marine Corps authorizes service stripes to those service members for every four years of service. In cases where a disciplinary infraction has occurred, the service member is not denied a service stripe but simply is authorized the standard red stripe design.
The Air Force mirrored the Army from 1976 to 2 May 1991 with an E-4 being either a Senior Airman wearing three stripes without a star or a Sergeant (informally referred to as Buck Sergeant) which was noted by the presence of the central star and considered an NCO.
