'''Shard cannons'''{{Ref/Book|Id=Enc22|Enc22|Page=327}}, also known as '''pulse beams'''{{Ref/Reuse|Enc11}}, are a form of heavy [[needler]] weaponry used by [[Forerunner]] [[Enforcer]]s.{{Ref/Book|Id=Enc11Enforcer|Enc11|Page=237}} Among [[United Nations Space Command]] personnel, shard cannons have also been given several colloquial nicknames including "'''Red Death'''" and "'''the Reds'''".{{Ref/Reuse|Enc11}} 

==Overview==
[[File:Pulse beam impact.png|thumb|250px|Pulse beam projectiles impacting a surface.]]
===Design details===
The shard canon fires a rapid stream of red [[Subanese crystal|Blamite]] projectiles at a high velocity. These projectiles are very similar in appearance to those of the [[Needler]], but do not share the "supercombining" or homing abilities of Needler rounds. Upon puncturing an enemy, the pulse beam's projectiles "shatter" within a few seconds.{{Ref/Game|Id=InGame|H2|Shard cannon in-game weapon}} They have an effective range of 150 metres (490 ft){{Ref/Reuse|Enc11}} and gradually lose altitude as they fly, giving Enforcers a decent advantage over the Flood as they can fire from long ranges and heights.{{Ref/Reuse|InGame}}

The weapon's similarities to needle weaponry of [[Covenant]] design have lent credence to the theory that the [[Sangheili]] may have created their own needler weaponry based on reverse-engineered shard cannons.{{Ref/Reuse|Enc11Enforcer}} It likely shares some overall characteristics with the similar [[shardstorm launcher]] and [[shard projector]] weapons.

==In-game information==
[[File:Pulse beam 3.png|thumb|250px|An Enforcer firing its pulse beam weapons on ''[[Sacred Icon]]''.]]
Enforcers generally fire pulse beams at infantry units only, saving the mortar weaponry for vehicle based units. When fired, waves of red projectiles are fired towards the Enforcer's enemies. These are difficult to dodge head-on, but can be easily avoided if there is suitable cover, or if the player keeps up a constant pace to the side. The weapon is used only against infantry, as it would be generally ineffective against most, if not all vehicles, as the driver or pilot is generally well defended or hidden from direct view. Therefore, the Enforcer uses it's mortar-like weapon to combat vehicles.

The weapon can easily defeat weak, unshielded units, such as [[Unggoy|Grunts]], and even [[Kig-yar|Jackals]] can have trouble using their shield to effectively block the projectiles. When used consistently, the weapon can keep an unshielded or wounded enemy pinned down for a considerable amount of time, and can be very distracting and frustrating when trying to defeat the Enforcer. Therefore, it is usually a preferable tactic to disable the Enforcer's weapons first.

==Trivia==
The shard cannon's official name was first given in the ''[[Halo Encyclopedia (2022 edition)]]''.{{Ref/Reuse|Enc22}} Prior to this, it was commonly known by the name of "pulse beam"; a fan-made term originating from Halopedia and one of several fan misconceptions copied from Halopedia and accidentally canonised in the ''[[Halo Encyclopedia (2009 edition)]]''.{{Ref/Reuse|Enc11}}
