ELI5:How do soldiers in the military not go deaf after about a week of deployment?

I've shot an AR15 before without earpro and I had ringing ears/impaired hearing for about an hour afterwards. I can't imagine several of those things going off at once on full auto. My ears would just explode.

The military has something called a teeth-to-tail ratio, which is the ratio of guys who normally pull triggers (infantry, artillery, armor) to those who support them (truck drivers, mechanics, cooks, supply folks and the like.)  The majority of most military forces are in the "tail" and they aren't dealing with loud noises most of the time.

Even the the troops in the "teeth" aren't in combat all the time, and when they do, they usually are wearing ear protection, or popping it in when things are going to get loud. (that is, if the NCOs are doing a proper job disciplining their troops.)
