Marines are known for many things: their tenacity for war fighting, spirit of brotherhood, and the ability to drink vast quantities of alcohol and still function are just a few. Marines also love to yell. Mostly at each other, but exceptions can be made. Go on to any Marine Corps base and your ears (if they work) will be filled with the distant echoes of asses getting chewed. Marines are taught to yell and to be yelled at as early as they step on those yellow foot prints; a lesson happily given by their Drill Instructors.
One of the most common complaints at the VA post-service is the ever-present, ever-annoying ringing in the ears known as Tinnitus. It’s almost a rite of passage for Marines, at least in the infantry, to say that you’ve entered and exited the Marine Corps with totally fucked ear drums. It means you’ve lived a full life! Full of explosions and loud noises, and you were man enough to do it without hearing protection.
Marines yell because they have to. With more yelling comes more hearing damage, and the cycle continues.
At the very least, you’ll have a few percentage points at the VA to look forward to when you get out.
