Every type of gun imaginable can be found in homes across North America, but explosive ordnance like rockets and grenades are hardly ever seen, much less used, outside of the battlefield.
So the odds you'll ever need to know how to survive a grenade blast are slim to none, however the odds all the curious minds out there are now dying to know how to survive a grenade blast "just because" are great.
Didn't feel like watching the entire video for answers? Here's the strategy in a nutshell:
As they explain above, the shrapnel (or fragments) from the grenade is the most dangerous part, not the blast itself. So, if you see one fall to the ground near you, it’s time to hit the deck. Turn and face away from the grenade, get at least 15 feet away, then lay on your stomach with the flat parts of your feet pointing toward the grenade. That will significantly reduce the chance of shrapnel hitting you, and if it does, there’s a chance it will hit the soles of your shoes, not your flesh. Also, if you see one fall into the water you’re swimming in, get out—don’t dive deeper. In that case, the shrapnel won’t get you, but the pressure created by the blast will compress your lungs and do some serious damage.
