So, you're in a firefight. Rounds are coming at you as you return fire, but you are so stressed you have lost fine motor skills and can't even use your fingers to drop the magazine. It's obviously a huge problem, but luckily YouTuber "Phuc Long" is here to show you how to use your gross motor skills to reload. Sort of.
On his channel Firepower United, Long demos an actual decent magazine change.
Which he says is "noooo problemmmmm." Then he goes to the gross motor skills, which is just... Well, you have to see it.
As a commenter says on another one of his videos, "Is that your real accent or are you just hard core trolling? Either way, I am a fan."
That said, if you actually need to learn to reload a weapon, maybe look elsewhere...
