Probably not. Not something I would do personally. But different strokes for different folks. I've seen guys join up to specifically be Boatswain Mates. Depends on their motivation. I would sure as heck make sure they are as informed as possible before they take any steps that could hinder their abilities. Also, if I were 26 or older and was wanting to start a career in the Navy I would think about who my peers would be if I were enlisted. You might be the same age as your chief, haha.
