Took this comment from spacebattles, the user is called someguy16, they were discussing the UNSC Marines vs. the US Marine Corps:
"Well, yeah. You see UNSC logistics are built around the holy grail of cargo aircraft, the Pelican, which enables their atrocious and lazy logistical practices. So the distribution of SAWs from the factory goes a bit like this. The commander gets a crate of SAWs before a deployment, but because the quartermasters are assholes even by real life standards, they can't be assed to fill out the paperwork to assign them to anyone. It requires a couple more forms to assign a SAW than an assault rifle, and fuck that shit. Emergency requisite forms are like... half a sheet. So it's best to just wait until the guys on the ground need them.
Fast forward a week. Private Jimmy heard from Sergeant Jackson that Captain Brown was told by Staff Sergeant Walt that 3rd battalion's Colonel Emery read about how Lieutenant Oswald saw these two privates talking about a a rumor that made it sound like a Pelican airdropped a bunch of supplies on top of Helljumper Corporal Miller's fire team right before it fought a Brute Chieftain. According to the legend, other than half a dozen assault rifles, two pistols, and a shotgun, they might have been given a SAW, too! And everyone's really pissed because they've been trying to scavenge together a SAW for half the Campaign and they hadn't even seen a magazine let alone a whole weapon!
Not that it matters anyway because supposedly the Master Chief traded a half dead plasma pistol for Miller's SAW, so the ODST only got to hold the mythical squad automatic weapon for around thirty seconds."
Needless to say, I laughed out loud.
