In his first few weeks, Naruto learned quite a bit about the Marine Corps. His first lesson was the the Marine corps can teach you a lot of things and does a lot of things which make no sense at all.
He joined an infantry battalion expecting to shoot weapons every other day and learning how to be an excellent machine gunner. What he learned instead was that all he really did was clean things. This was especially true of the new guys. All he did was clean the bathrooms which were now called heads or clean his rifle. He became an expert at finding dust in the most random places and wiping windows and mirrors to look busy. In the Marine Corps, you are never finished until time is up, so you just wipe things down to look busy. Yes, Naruto quickly learned that every Marine is a janitor as well as a rifleman. He also learned how to skate to get out of doing absolute bullshit. Like cleaning the toilets two times in a row. For no reason at all.
"Hey Uzumaki, go clean the heads out you silly boot," exclaimed someone that was a higher rank than him. He didn't give enough of a fuck to care about who they were.
"Sure thing," replied the blonde.
As he stepped into the bathrooms, he quickly smelled the overwhelming stench of bleach. Oh good fluoride. It meant that it was probably already clean. Which means he didn't have to do anything. He stepped inside to piss and blue falcon everyone that cleaned it. To his surprise, he found a Shikamaru Nara cleaning the stalls.
"Hey asshole, if you're going to piss find somewhere else. I just cleaned these," Said a flustered Shikamaru Nara. He was all about the skate life.
"Sure thing boss."
Another thing Naruto learned was all the terminology used by the Marine Corps. A bathroom was a head. A buddy fucker was a blue falcon. A POG was a personnel other than grunt.
"Hey Hatake, remember those POGs that tried to yell at us when we had our hands in our pockets? Fucking assholes, ahahaha," yelled Asuma Sarutobi.
"Yeah. I fucking hate POGs. They think they rate when they didn't go infantry. I hate POG Marines dude."
"What is a POG?" chimed in the curious blonde.
"A POG is a Personnel Other than Grunt. They are assholes who enlisted in jobs like combat engineer or intel and think they know what the actual Corps is like," answered Corporal Hatake.
"Oh. What a bunch of fucks," said the Naruto with a rather monotonous expression.
"Shut up and go clean the head. Boot."
Yes, Naruto quickly learned how the Marine Corps did things. He came to the conclusion that their leadership really didn't know what it was doing. ANd because of this, they always did things in a way that could have been much easier and made much more sense.
Naruto quickly learned a lot about the Marine Corps. Quite of bit of his newfound knowledge was not positive.
