>>511080869> pulling the pin on a grenade you are not certain about, if it's been modified or notuh oh! bad idea, anon!
now you're dead.
it could be rigged to blow up immediately when the pin is pulled, as a booby-trap for anyone who should not have found them but did, then decided to "dispose" of the grenades by using them.
technically correct action, but horribly wrong method.
the correct method would be taking known explosives you already possess, and then using them to detonate-in-place or otherwise destroy any other explosives you find. this includes shooting the grenade from a safe distance with a large caliber gun from behind a shield to physically open up and destroy the components. thus, you're not taking chances with anyone's life, as nothing is worth the risk of tampering with unknown explosives.
but if the pin really had to be pulled, i would consider the difference between:
A. attaching the string to the pin first and rolling out the length of string string second
B. rolling out the length of string first and attaching the string to the pin second
if you can't figure out why one of these will kill you and the other one will save you, do not ever tamper with explosives; failing the order of operations murders the incompetent.
