Frag Mine (Fallout 3)

The Frag Mine looks like a tan shaped disk with a black gear and red button on top. The tan paint is most likely used to camouflage the mine out in the desert covered Capitol Wasteland. The Frag Mine will begin beeping when a target comes within a short distance to it until it is disarmed or it detonates. The time until detonation depends on the Explosives skill of the person setting it off.

Frag Mines can be disarmed with a high enough Explosives skill or simply avoided with the Perk: "Light Step".

Usage
Frag Mines will become live and likely to cause instant death after it's dropped into NPC's pants (inventory) via theft.

Frag mines are useful weapons against a Mirelurk. These creatures have very tough armour but very low hitpoints. You can find yourself wasting a lot of ammo trying to kill them. A Mirelurk will move very slowly towards you, since it only ever attacks with melee. Just drop a frag mine and retreat. It takes 3 frag mines to kill a Mirelurk.

When you plant a frag mine, you can walk over it and it will not explode. If the frag mine is not needed, then you can simply walk over to it, disarm it, and pick it up again so it does not go to waste.
