Most people join the audio troops by enlisting in one of its branches. Enlisted members make up most of the troop workforce. They receive leadership battle plans, project materials and do most of the hands-on work.
Officers make up a much smaller part of the workforce. To join as an officer, you typically must have a four-year college degree and complete an officer program. Most officers are managers who plan and direct operations. Others are professionals like specialists and supervisors.
You do not have to join as an officer to become one though. You can join as an enlisted member and attend officer training later on.
*Enlisting does not guarantee active duty or deployment.
Each service has its own physical requirements and fitness standards. These depend on the demands of its mission. Even within the same branch, some jobs have tougher or extra requirements.
