“A piss tube is exactly what it sounds like. When we first got here we stabbed a six-foot PVC pipe into the sand at an angle so everyone could piss in it like a wall urinal. Nicer outposts have a series of them lined up side-by-side. It helped with the smell because it spread the piss out over a dozen feet or so. We only had the one, though. Just a nondescript tube sticking out of the sand with no walls or ceilings, leaving you and your fellow Marines to flop your cocks into a huge gray tube that smelled like calcified piss and dip spit. War is hell”
