Editing M'tara-pattern focus rifle

The focus rifle copies some elements of the [[Sentinel beam|sterilization beams]] employed by [[Aggressor Sentinel]]s{{Ref/Reuse|OSFM}} and [[Z-510 focus turret|focus turrets]]{{Ref/Book|H4EVG|Page=103}}, though the magnetic accelerators and particle guide beam emitters are novel creations of Covenant origin. These features present a counterpoint to the idea that the Covenant never innovated when it comes to technological development.{{Ref/Book|Id=OSFM|OSFM|Page=193}} The focus rifle's electromagnetic compositors are a design shared with the {{Pattern|Elutuzem|stalker rifle}}.{{Ref/Book|Enc22|Page=479}} Instead of firing a single beam of ionised hydrogen in one shot like the Covenant [[particle beam rifle]]s, the rifle fires a continuous purple-tinted beam of magnetically contained plasma, similar in operation to a [[Sentinel Beam]], the [[Forerunner]] weapon from which the ''M'tara'' was reverse-engineered. The plasma is formed in a cylindrical module and directed through a channel of electromagnetic coils, forming a precise beam. Like most Covenant infantry weapons, the weapon draws its power from a battery. The weapon requires high power expenditure and the battery is easily depleted.{{Ref/Reuse|EVG}} The exact mechanism by which it functions was under investigation by the [[United Nations Space Command]] as of August 2552.{{Ref/Reuse|bnet}}
