Does jumping on a grenade actually stop it?

Yes. Grenades aren’t that powerful. And the explosive force they generate is largely to break the grenade shell up into fragments/shrapnel, which actually cause injury. Jumping on a grenade is near certain death, but also pretty certain to prevent injury (certainly serious injury) to others nearby.

Can you contain a grenade with a helmet?

Putting a helmet or some similar object over the top of an explosive device, such as a grenade, would only serve to direct the blast, slightly. The helmet would most likely become a lethal projectile itself. One cannot ‘reduce the blast’ of a device such as a grenade.

How many seconds does it take for a grenade to explode?

From pulling the pin and throwing a grenade, it usually takes anywhere between two to six seconds before detonation occurs.

How do you throw a grenade with your hands?

Assume a natural stance with the weight balanced equally on both feet. Hold the grenade shoulder high and hold the nonthrowing hand at a 45-degree angle with the fingers and thumb extended, joined, and pointing toward the intended target. Throw the grenade with a natural motion,…

How long does it take to pick up a grenade?

Assuming a 4 second fuse length, two of which are spent in flight, you have just two seconds to notice the grenade, react, reach down, pick it up, plant your feet, lift up, and throw it far enough that you’re clear of the blast radius. Not going to happen except in the ultra-rarest of situations.

What if the grenade had been on the ground next to him?

If the grenade had been on the ground next to him, this helmet would have been largely intact but he still would likely have been killed. What this illustrates is how important minimizing exposure, and maximizing cover are when dealing with a grenade.

Can you run with a fragmentation grenade?

The generally accepted fragmentation radius for a frag grenade is 30-35 feet, and the fuse length will be between 3-5 seconds. So usually running isn’t going to be an option for you. If you can take cover, do so. If not, hit the deck and get as low as possible, as the majority of the fragmentation will go upwards.
