Kig-yar Sniper

Jackal Snipers are newer rank additions for the Jackals of the Covenant. Unlike standard infantry Jackals, Jackal Snipers do not carry Jackal Personal Arm Shields. They wield long range weaponry, serving as the Covenant's answer to UNSC Marine sharpshooters.

Jackal Snipers are very different from all the other types of jackals. Jackal Snipers do not carry energy shields but instead they use both hands to man the beam rifle or a carbine. The Covenant beam rifle is a very powerful sniper weapon; it may take your shields down in Easy or Normal but in Heroic or Legendary the beam rifle may only take one shot to end the life of the player. Jackal Snipers are not like the regular Jackals; they do not keep shooting if you are close, but instead drop their beam rifle, take out a plasma pistol, and retreat.

Killing Jackal Snipers
The best way to kill a Jackal Sniper is to use either a Beam Rifle/Sniper Rifle, or a M6C Magnum Sidearm for an instant kill. The BR55 Battle Rifle and the Covenant Carbine also delivers an instant headshot kill.

Unlike all other Jackals, these guys are slow but have compact bodies. The Beam Rifle has to be the best weapon on them. One shot, one kill. Be sure to take cover as they can kill you with a single shot. Switch to the SMG and blow away any retreating Jackals.

Trivia
In the level Outskirts, there is a Jackal Sniper in a tower that when killed, an "invisible Jackal Personal Arm Shield" collapses, and you can see the tell-tale blue electricity and noise.
