I think a good common one is explosions that throw people at least 10 feet without killing them. If the shockwave is strong enough to do that, isn’t it strong enough to tenderize and completely disable all of your internal organs as well?
Shrapnel-creating explosives is used for open ground. In closed-in terrain, blast explosives is always going to be more effective. That's why the infamous "potato masher" grenade of the Germans was blast-only - it's far more effective at killing people inside trenches and bunkers. The US used the WW1-vintage Mk.3 grenade for that same purpose up until very recently.
I think you are probably right but I always imagine it like wind in a sail. It's strong enough to push a ship but not rip the sail due to surface area. I can at least pretend that's the case. 😆
It can happen, but not at the rate you see in movies. Explosions in real life is far, far more brutal than they are in the movies. Blast waves can liqefy bone - something the writers of zombie media never seem to understand.
