How many service ratings does the AM rating consist of?

The correct answer is that the Aviation Structural Mechanic (AM) rating consists of two service ratings. This reflects the structured categorization within the Navy's training and career progression system, where various service ratings are grouped to streamline the specialization process and enhance operational efficiency.

For the AM rating, these two service ratings are typically related to the specific areas of expertise required in aviation structural maintenance. Each service rating within the AM category encompasses different skills, responsibilities, and technical knowledge that a sailor must acquire and master to effectively perform their duties in naval aviation maintenance.

By having two service ratings under the AM, the Navy ensures that personnel can be effectively trained and deployed according to the demands of their specific roles, while also providing opportunities for career advancement within the aviation maintenance community. This dual-system approach helps maintain a high standard of readiness and capability within naval aviation.
