Kig-Yar Major

Jackal Major is an elevated rank for more experienced Jackals of the Covenant. They are characterized by their orange shields, and usually wear armor that is golden brown in color, though this is not always the case. They are seen commanding Jackal Minors or Grunts in combat.

In Halo 3, their shields appear to be light purple.

Combat
Jackal Majors almost always wield Plasma Pistols which they are fond of overcharging. Be very careful when attacking them from the front. These Jackals are trickier than their less experienced counterparts. They are better at blocking themselves with their shields, and can usually roll out of the way of a Frag Grenade. The best way to kill them is to Melee them, or use a M6C Magnum and land a head shot for an instant kill. This will also work with the Covenant Carbine or the BR55 Battle Rifle as well, or alternatively using a Sniper Rifle to kill them from afar. With precision weaponry(to help combat Jackal shields) fire at the shield embrasure on their arm which will cause them to reel back in pain allowing for a brief oppurtunity for a headshot. This will also occur if you shoot at the small area in the shield where the jackal fires from.

Like Minor Jackals, Major Jackals are not tough and should be taken down at your own pace. However, they are rarely found alone, often found leading Lances of Grunts as well as other Jackals. With the IWHBYD skull on, you can hear them saying "go you noobs" to his fellow comrades.

Appearances
They appear in almost every level in Halo: Combat Evolved, Halo 2 and Halo 3, with a few exceptions, such as The Library in Halo: CE or The Oracle (Level) in Halo 2. They are not in the Halo 3 levels Cortana, or Halo.

Halo 3
Though they are not listed in the Bungie.net stats, Jackal Majors are likely in Halo 3 as the violet shield bearing Jackals. On Legendary, these are more common then their blue shielded counterparts, and with the Thunderstorm skull active, violet shielded Jackals are the only shield color that appear, which suggests that they are of a higher rank than their blue shielded counterparts.

Trivia
Sacred Icon in Halo 2.
 * The sudden change of the Major Jackals' shield color (from yellow to pink) is currently unknown, perhaps it was just a scripted promotion following the wake of the Great Schism.
 * It has been confirmed that in Halo 3 the Jackals with the turquoise shields are in fact Minors and the Jackals with the violet and pink shields are Majors.
 * In Halo: Combat Evolved for the PC, it looks like the textures, coloring, and all-out graphics were never completed or they didn't transfer from the Xbox to the PC very well. So Jackal Minors and Jackal Majors have the same shield color (turquoise). In the Xbox version, the Jackal Majors have light-orange shields while the Minors have dark-blue shields.
 * The only point so far in the Halo series where the player has Jackals (Jackal Majors usually) for allies is the level
