Mate, Gunner's Mate, Machinery Repairman, Operations Specialist, and Engineman. My aim in life is to know my job; to know everything that pertains to practical gunnery and ordnance. As long as there is any operation or piece of equipment I do not fully understand, my job is not complete. In the event of war, I must be prepared for any emergency. I must be capable of and competent to fill my station, or perform any operation in the weapons department of my ship; to assume command of, spot, or control the fire of any battery. In addition to being competent to perform any operation, I will strive to know my maintenance duties so well that I may maintain the battle efficiency of my ship, even on a darkened ship, under enemy fire. This to the end ... that the ship may fight as long as she is afloat! See also List of United States Navy ratings References United States Navy ratings
