Pulse Grenade (Fallout: New Vegas)

The pulse grenade is a thrown explosive

Gameplay
When combined with mid to high explosives skill, the pulse grenade makes very short work of any Sentry Bot, Protectron, Mister Handy, or any other drones or turrets. Visually, when used the pulse grenade will make an electrical sphere, damaging anything inside. It can be enhanced with various perks, such as Demolition Expert, and Splash Damage. It only does light-to-moderate damage to non-robot enemies, but is also very effective against enemies wearing power armor.

Unlike in Fallout 3, pulse weapons in Fallout: New Vegas do have an effect on power armored non-player characters and the player. Use extreme caution when using any pulse weapons near friendly power armored non-player characters, or when wearing power armor yourself.
