The Stick It medal (also called Grenade Stick) is awarded for killing an opponent by sticking a Plasma or Spike Grenade to them. It is available in all Multiplayer gametypes and has a Bungie difficulty rating of 3 out of 10. It is represented by a 16-pointed bronze star with a 16-pointed blue star in it, and a blue sphere inside of that. After you kill an opponent by sticking a grenade to them, a message appears on your screen that says: "You stuck (player's name)." This is also a medal in the Halo 3 campaign. Sticking is very easy to do if you have the Catch Skull, because when an enemy leans to throw a grenade at you, they cannot dodge any grenades thrown at them during this time.
