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.
In the Air Force the rank below sergeant is Senior Airman, and in the Marine Corps it is a Corporal. In the American Army, a sergeant was the 3rd rank in promotion and wore 3 stripes. However, sergeant can be a generic term for any non-commissioned officer above 3 stripes.
