Armor Ability

Armor Abilities are exclusive gameplay enhancements featured in Halo: Reach. It is a refined version of Halo 3's Equipment feature, where instead of being used once, each ability will be reusable, with a cooldown time between uses.

Sprint
Sprint allows the player to move at increased speed for a certain length of time. It is highly useful for players who enjoy using the Energy Sword or Gravity Hammer.

Active Camo
The Active Camo provides players the ability to have Active Camouflage for a period of time, similar to the Thel 'Vadam's active camo from Halo 2.

Jet Pack
The Jet Pack ability allows players to fly upwards, with the use of a jet pack. It will be useful for evading splatters, grenades, and navigating maps.

Dodge Roll
It is currently unknown if the Dodge Roll, a forwards roll to evade danger, is an ability or if it is simply triggered through a certain command, regardless of armor or player character. It currently appears to be limited to Sangheili as no Spartans have been seen using it to date.

Invincibility
Like the Dodge Roll, "Invincibility" as it is being called, was revealed in Bungie's Halo: Reach Multiplayer Trailer during the time of 0:22 and 0:24. It appeared to create a very powerful shield around the user, then detonate in a relatively large radius, which in the trailer, managed to kill a nearby Ghost.
