Which naval rating is abbreviated as ET?

The correct choice is Electronics Technician, which is abbreviated as ET in the naval rating. The role of an Electronics Technician is crucial in modern naval operations, as these personnel are responsible for the maintenance, repair, and troubleshooting of electronic equipment aboard ships and submarines. This includes navigation systems, communication systems, radar equipment, and other electronic devices essential for mission success and safety at sea.

In the context of naval ratings, the abbreviation specifically highlights the focus on electronics rather than general electrical work, which could lead to confusion with Electrician's Mate, a different rating. While Electrician's Mate involves working with electrical systems, Electronics Technician is distinctly centered on electronic technology, pointing to a specialized skill set in dealing with advanced electronic systems. Recognizing this distinction is key in understanding the broad range of responsibilities assigned to different naval ratings.
