If you’ve never had the pleasure of being near an M777 Howitzer when it’s fired, suffice to say that ear plugs aren’t really an option. The explosive power unleashed by this artillery isn’t merely something you hear, it’s something you feel as the air is compressed out of your lungs and your whole body finds itself temporarily stunned by how it was impacted all at once by a shockwave. When you know it’s coming, it can be a truly awe-inspiring experience. If you’re peacefully sleeping nearby, however, it’s probably just about the world’s worst wake-up call.
