There’s not much hugging or head-patting, and superiors don’t always have the authority to offer a serviceman a raise or promotion. When a member of the Army, Navy, Air Force, Marine Corps, or Coast Guard wants to show appreciation, love, sympathy, or professional connection, they can use challenge coins.'
