Why Do Soldiers Tap Their Magazines on Their Helmets?

You've seen it in the movies: a soldier raps a fresh magazine against his helmet before loading. We read ten Army manuals and one Army comic book, 1942 to 2017. None of them tells a soldier to tap a magazine on a helmet. One Marine Corps manual does say "tap the back of the magazine." It just never says on what. 00:00 You've seen it in the movies 00:51 Part One: The obvious answer 02:53 Part Two: What's on paper 06:20 Part Three: What nobody tells you 09:24 A ritual Standard Issue explains why the military does what it does. Every fact in this video is sourced below. What we could NOT verify, and say so in the video: Where the helmet tap started. We found no manual, report, comic panel or photo caption from the 1960s that describes it, and no source that connects the M16's magazine problems of 1966-67 to the habit. Whether it works. We did not find a published test. When the "tap the back of the magazine" sentence first entered the Marine Corps manual (1999 is the oldest edition we could read).
