Jiralhanae Power Armor

"He's got Power Armor, Chief! Take down his shields before you get close!"

- Marine during first encounter on Sierra 117

The Power Armor, is the Jiralhanae armor featured predominantly during the events of the Covenant Civil War. Though in use since 2524, it saw widespread field operations only sometime during the later years of the war. This armor made its in-game appearances in Halo 3.

Function
Power Armor serves as extra protection to the Jiralhanae, who before the Civil war were generally poorly armored (with a few exceptions, such as the crew of the Rapid Conversion). Unlike Spartans and Sangheilis, it is more of a deflection armor (e.g bullets will "ping" off the armor with the help of the shields). It provides protection from all ballistic and plasma weaponry, and even light shrapnel/explosive protection, until failure of the shielding. It also provides light protection from the environment and other elements.

The armor displays the rank of the Jiralhanae wearing it, usually through the color or complexity of the armor. The system is similar to that of the other Covenant races, although it seems to follow its own nomenclature.

In Halo: Contact Harvest, it is said that plasma was leaking out of a Jiralhanae's power armor as the shielding failed, which can also be seen in Halo 3 when the armor takes extensive damage.

Advantages
As with all Energy shielding, it is very good at absorbing damage from projectile weaponry. It also seems to solve the problem the Covenant may have had with finding energy shields that would work on Jiralhanae and be reasonably affordable. They also appear to recharge generally faster than the Elite's version.

It comes in many varieties, some with more strength than others, and some with useful secondary applications (such as the built in Cloaking in Brute Stalker Power Armor, and the inability to stick grenades or Needler rounds to Brute Chieftain Power Armor).

It does not give off as much of a glow as Sangheili and Spartan Energy shields when hit, which can be useful for concealing the wearer's position, and since it falls apart once the shields go down, the Flood cannot use it for themselves. However, if the Flood infects a Chieftain whose armor doesn't fall off, it will still become a minor Brute combat form due to programming restrictions.

Disadvantages
It is variable in strength, ranging from being inferior to the Sangheili Personal Energy Shield and MJOLNIR Armor shielding to being double the strength of one. It is easy to see how damaged the armor currently is via the luminosity of the armor's lights and the presence of sparks and smoke, which signifies that the armor's shielding is almost depleted. It is unable to recharge after complete overload (unlike Sangheili and Spartan shielding), and in fact, falls apart.

This may be caused by the system being less robust than other shielding systems (but is most likely a game play design choice.) However, as long as the system is not overloaded completely, it recharges as rapidly as the other systems do. Still, the Brutes are already naturally resilient, and can withstand substantial amounts of damage even without their armor. However they are very susceptible to headshots once their power armor fails.

It also falls prey to the usual weaknesses of energy shielding, including weakness to plasma weaponry. Of course, overcharged Plasma pistol shots can take it down in one hit pertaining to the difficulty.

Trivia

 * In Halo 3: ODST the Jiralhanae are outfitted with power armor. However, the Jiralhanae encountered by Blue Team at the Centennial Orbital Elevator are unarmored, despite the engagement occurring some two weeks after the events of Halo 3: ODST.
 * In Halo Wars, the Jiralhanae commanded by the Jiralhanae Chieftain wore power armor, however their armor did not break off after sustaining damage and instead if the user takes too much damage, he would just die wearing the armor.
 * Also in Halo 3: ODST, Brutes power armor would flare up due to the shields taking fire, much like Sangheili's and Spartan's have been doing since Halo: CE. . Additionally, Brutes will no longer flinch from shots from Sniper Rifles, etc. whilst the shields are still active.
 * In the marketing campaigns for Halo 3 and Halo 3: ODST, the power armor worn by the Brutes does not deflect incoming damage, as Brute infantry are repeatedly struck by incoming fire as though they had no shields. This can be seen in Halo: Landfall and We Are ODST.
 * In Halo Wars the brute armor was present disregarding the fact that they were poorly armored until after the civil war began.
 * It is possible that the armor never saw extensive action before the Civil War because the Sangheili used their political influence to restrict the military power of the Jiralhanae, similar to the situation with the Rapid Conversion.
