Hey Adm. Lee, you're welcome
While I have no problem with any website trying to explain the realities of such things, it annoys the hell outta me when they don't properly research it.
So Cracked asked some serving soldiers about their experiences and wrote the article from that info, I get that, but the article really needed more clarity and perhaps I'm being overly harsh because Cracked authors don't necessarily know the right questions to ask...
However...
A website like Cracked doesn't just have thousands of people reading their articles, they have millions. Some of those readers take the info they got from Cracked and become "Instant military expert, just add Cracked" and further disseminate that flawed info - thereby defeating the point of the article in the first place. They really, really, REALLY need to get it right and that means doing a little more research but in this day and age with many military themed forums available, it's easier than ever - you don't even have to go to a library anymore!
One other thing to mention about runaway guns that I forgot to add while I was so steamed up - if you're using disintegrating link ammo, you're trained to break the belt as close to the feed pawls when a runaway occurs thereby limiting the number of rounds available for the gun.
Although I've never tried this, "soldier's stories" claim even twisting the belt so that it can't fed properly is allegedly enough to stop the runaway because the gun uses a recoil operated mechanical feed and while it is powerful enough to pull in a 100-rd belt, it's not strong enough pull a twisted belt back into line.
But take that as hearsay, because as mentioned, I haven't tried it and I don't know anyone else who has although it does sound as though it would work.
