As a former Marine infantry officer, I found it illustrating to pick up this month’s issue of the Marine Corps Gazette and discover that our infantry is a “cult-like brotherhood ... the one place where young men are able to focus solely on being a warrior without the distraction of women or political correctness.” I will admit that I found this to be a rather sweeping assessment, but it’s how at least one Marine officer who has never served in the infantry imagines it to be. In truth, Capt. Lauren Serrano is not entirely wrong. Marines do “fart, burp, tell raunchy jokes, walk around naked, swap sex stories, wrestle,” etc. Although to be fair, the Marine Corps infantry --- or male Marines alone for that matter --- does not have a monopoly on juvenile humor (see here or here for NSFW examples). And while Serrano failed to mention Marines lighting fires (my experience shows that grunts will usually build a fire before they get naked), I doubt many officers would disagree with her general observations about infantry behavior.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
