The '''M66 light railgun''' ('''M66 LRG''') is an anti-vehicle weapon system mounted in pairs to the [[SP42 Cobra]] self-propelled artillery vehicle, in conjunction with the larger [[M98 light railgun]].<ref name="EVG">'''Halo: The Essential Visual Guide'''</ref><ref name="Guide">'''[[Halo Wars: Official Strategy Guide]]''', ''page 43''</ref> The M66 is often mounted in pairs to [[Firebase|prefabricated]] [[Base turret|automated defensive turrets]] for use as a static defensive measure.<ref>'''Halo Wars: Official Strategy Guide''', ''page 30''</ref>

==Overview==
The M66 LRG is a powerful anti-armor weapon that fires 30&nbsp;mm high-density ferrous projectiles at ultra-high velocity. The velocity of these projectiles allows them to penetrate armor at extreme range and with superior penetration to the [[M512 smooth-bore high-velocity cannon|M512 90 mm cannon]] used by the [[M808 Scorpion]].{{Ref/Reuse|EVG}}{{Ref/Reuse|Guide}}<ref name="Site">[http://www.halowars.com/GameInfo/vehicledepot.aspx#Cobra Halo Wars Official Site - Cobra]</ref> Though the weapon performs similarly to the [[M68 Gauss cannon]], the M68 is a coilgun, which operates on different principles from those of a [[railgun]].

When twin-mounted on the SP42 Cobra and on automated turrets, each weapon is fired alternatively, as the energy required to fire both railguns together is beyond what the platform is capable of producing. This alternating also improves the weapon's rather low rate of fire, maintaining more consistent power output.{{Ref/Reuse|Site}} 

==Trivia==
The ''Halo Wars'' official website initially identified the weapon as the '''M66 50&nbsp;mm Gauss cannon'''. After the game's release, references to the M66 Gauss cannon were removed from official material and the weapon was renamed the LRG railgun. It was stated that the Cobra uses a pair of 16 megajoule LRG railguns when in normal mode and a single 8 megajoule version when locked down. ''[[Halo: The Essential Visual Guide]]'' retconned the 16MJ version of the LRG railgun into the M66 30&nbsp;mm light railgun, while it retconned the 8MJ version into the M98 105&nbsp;mm light railgun.

-Though the weapon performs similarly to [[Gauss cannon]]s such as the [[M68 Gauss cannon|M68 model]], the M68 is a coilgun, which operates on different principles from those of a railgun.
+When twin-mounted on the SP42 Cobra and on automated turrets, each weapon is fired alternatively, as the energy required to fire both railguns together is beyond what the platform is capable of producing.

+==Trivia==
-The M66 railguns are most notable for their twin installment in the turret of the [[SP42 Cobra]], allowing the vehicle to serve as an agile tank-hunter and anti-fortification vehicle.{{Ref/Reuse|Enc22}} They are mounted on the Cobra alongside the larger and more powerful [[M98 light railgun|M98 105mm light railgun]].{{Ref/Reuse|EVG}}{{Ref/Reuse|Enc11}}{{Ref/Reuse|Enc22}} M66's may also be installed as an optional anti-vehicle mounting in the [[M5 Talos]] automated turret system installed on [[Firebase|prefabricated bases]].{{Ref/Reuse|PrimaTurret}}
