H-165 target locator

The H-165 FOM or Target Locator is a United Nations Space Command piece of equipment. It is a compact, handheld laser pointer designed for acquiring and designating targets for small-scale orbital bombardment from an orbiting UNSC Starship. While similar in function to the laser designator, the Target Locator is much smaller and can be held with one hand. The Target Locator also has a scope.

The Target Locator appears as a weapon in Halo: Reach. When the trigger is held down for three seconds, a green laser beam marks the targets, and a red circle is projected on the ground around the target area. Once the target has been locked, seven missiles strike the designated area from above, doing a large amount of area damage.

Trivia

 * Destroying two vehicles with a single shot from the Target Locator in the third Campaign mission unlocks the Achievement "Two Corpses in One Grave." This achievement's name is reference to a line spoken by the Gravemind and is similar to the Halo 3 Achievement "Two for One."
 * The Target Locator is available only in Firefight and Campaign. It does not appear in Matchmaking or Forge, presumably for balancing reasons.
 * The Target Locator is the only weapon in the game not affected by the infinite ammo selection in custom games/custom firefight matches, along with a turret that has been disconnected from its base.
 * In the E3 Firefight demo, the Target Locator was labeled as the "Laser Designator" when a player picked it up. In the final game, it is labeled as the "Target Locator".
