Laser Kill

Laser Kill is a Medal awarded in Halo 3, Halo 3: ODST and Halo Reach for killing an enemy with the Spartan Laser, awarded for any kill with the Laser (other than melees) due to the unwieldy charge time and precise accuracy it takes to destroy a target with the weapon. It is represented by a gray cog shape with a black circle that in turn has a red dot in the center. As this medal is awarded, a message appears on the screen, saying "You lasered (player)".

Trivia

 * This medal bears a strong resemblance to the viewing port of Hal 9000, an AI from the movie "2001: A Space Odyssey"; it has a dark circle with a single red dot in the center.
 * In Halo 3 the "You lasered (player)" appears to be glitched, because on occasion, when an ally lasers an opponent, it will only say "(Ally) killed (player)".
 * You can also get this medal by lasering an enemy's vehicle while they're in it. An easy way to get multiples of this medal is to destroy a vehicle with multiple passengers with the laser, you will get one for each person in the destroyed vehicle.
 * The medal resembles the barrel of the weapon with the red dot being the charged laser.
 * The player will get 3 of this in Halo 3: ODST Firefight when they laser a Wraith, one for the driver, one for the turret and the final one for the tank itself.
 * Earning Laser Kill medal by killing a Banshee in Halo 3 campaign or matchmaking will unlock the Too Close to the Sun achievement.
 * Earning a Double Kill Laser Kill with a single Spartan Laser Shot in a Halo 3 free for all ranked match unlocks the Two for One achievement.
 * Earning 10 Laser Kill medals in the Halo 3: ODST level ONI Alpha Site will unlock the Laser Blaster achievement.
