You know what makes more sense? That he has earplugs to go with a pair of big, loud guns, so edited to that effect. [@PharaohAtem]

Yeah that works its a simple salutation although if he wore then during every battle that he needs his big loud guns it would make it more difficult to communicate and coordinate with as he wouldn't be able to hear the others. But ultimately its your character so its up to you what you do with it.
