What does a gunnery sergeant mean?

..... your husband should be bragging to you. I haven't heard of Gunners Sergeant (I am a soldier), but I have heard that the US Marine Corps has this rank, but it only exists in the US Marine Corps, and the US Army, Navy and Air Force do not have this name. The English name is "Gunnary Sargent", and the pattern is two downward folding rods with two rifles in the middle. This rank is higher than sergeant, staff sergeant and staff sergeant, and lower than master sergeant. Usually the backbone of the battle.
