The term '''active camouflage''' (often shortened to '''active camo''' or '''av-cam''') refers to various light-bending technologies, both [[United Nations Space Command|UNSC]]<ref name="goo">'''[[Halo: Ghosts of Onyx]]''', ''page 291''</ref> and [[Covenant Empire|Covenant]]. Most commonly, the term is applied to Covenant-developed cloaking equipment. | |||
==Description== | |||
Technically, active camouflage is not quite invisibility, though it is very similar. Rather, it is the term that is used to describe a broad range of technologies that allows a wearer or object to blend in with its terrain, mimicking the environment around it perfectly, though in two dimensions. There are a variety of ways to do this, though the UNSC uses [[photoreactive panel]]s on its [[Semi-Powered Infiltration Armor]] and [[UNSC prowler|Prowler]] stealth ships for optical camouflage, adapting to account for movement. | |||
Though it has never been elaborated on in detail, it is suspected that Covenant versions of the concept use [[Wikipedia:Phased array optics|phased array optics]] to project a three-dimensional [[holography|hologram]] of background scenery around the wearer of the system, effectively ''bending'' light, a task well within the Covenant's [[Technological Achievement Tiers|tier two technology level]]. The technology can be utilized on human armor systems, such as the MJOLNIR armor, but the UNSC has only developed rough equivalents.<ref>'''[[Halo: The Fall of Reach]]'''</ref> | |||

Covenant active camouflage technology uses a field of energy to bend light around the user, thus making them effectively invisible. The armor used by [[Special Operations Sangheili|Spec-Ops]] and [[Stealth Sangheili]], as well as that of [[Arbiter]]s, [[Jiralhanae Stalker]]s and even certain [[Sangheili Zealot|Sangheili Zealots]]<ref>'''Halo: Reach''', campaign level ''[[Tip of the Spear]]''</ref>, include built-in active camouflage generators. These built-in generators have a severe drawback in that they divert power from shielding equipment. Troops equipped with permanent active camouflage generators tend to have weaker shielding than those not equipped with an active camouflage generator. | |||

Arbiter [[Ripa 'Moramee]] was equipped with an active camouflage generator capable of generating a near-perfect cloaking field indefinitely. Arbiter [[Thel 'Vadam]] was also equipped with an active camouflage generator, but the device was capable only of providing a cloak for a few seconds, and although 'Vadam was equipped with personal shielding, his shields were relatively weak for an individual of such high rank, equivalent to those of a [[Sangheili Minor]]. | Arbiter [[Ripa 'Moramee]] was equipped with an active camouflage generator capable of generating a near-perfect cloaking field indefinitely, but had no energy shield generator and was forced to rely entirely on the protection of his armor plates.

For personnel not equipped with built-in active camouflage, it can be provided by a variety of devices. Typically, the energy used to provide the effect is suspended inside a small, transparent pyramidal container, or a larger spherical force-field. Personnel can use the light-bending energy by coming into physical contact with the container or force-field, which will cause it to break and release its contents. Upon release, the energy envelops the wearer and bends light around their skin; armor or [[energy shielding]], conforming to their form and rendering them almost invisible. After a short period of time, the energy will gradually dissipate and wear off, slowly revealing its user. The active camouflage provided by these devices lasts for ten seconds, and only prevents visual detection; those using active camouflage can be observed by other means, including motion tracking, noise, and environmental disturbances such as footprints on soft terrain. | For personnel not equipped with built-in active camouflage, it can be provided by a variety of devices.

Covenant active camouflage will easily cloak its user, but its effect does not completely extend to items in the user's possession; [[human]] [[weapons]] are easily cloaked by active camouflage, but Covenant weapons are visible even with active camo, as the light-bending energy cannot mask the glow of the weapons' plasma. In ''Halo: Combat Evolved'', however, plasma glow is hidden quite well by the powerup. | |||

However, it is difficult to spot a camouflaged opponent from a distance using a scoped weapon -- actual physical proximity is required to reliably spot a person using active camo. It should be noted, though, that active camouflage does not mask environmental effects such as footprints, meaning that it is not as effective on soft terrain such as snow. | ||

The | The shielding provided by Covenant active camo can be disrupted if projectiles pass through it; such a disruption weakens the invisibility effect and temporarily reveals the wearer. The powerup can be disrupted if the wearer fires shots or if the wearer is hit. It also progressively worsens: the longer the wearer fires (or is hit), the more visible they become. Once the disruptions end, however, the wearer quickly regains their invisibility. | ||

In addition, [[SPARTAN-II Program|SPARTAN-IIs]] [[William-043]] and [[Kelly-087]] employed talc powder in order to overload the camouflage on [[Reach]] in order to find them.<ref name="firststrike"/> | |||
==UNSC active camouflage== | |||
The UNSC has developed several varieties of active-camouflage technology. These do not utilize the same light-bending energy as Covenant active camouflage and are generally less effective. The most common form of human active camouflage technology operates on a different principle than the Covenant counterpart, using [[photoreactive panel]]s to impersonate the surrounding environment like a chameleon. A device known as the [[camouflage cloak]] can hide the wearer's infrared signature, beside serving as a form of camouflage.<ref name="goo"/> | |||
The [[Semi-Powered Infiltration Armor]] used by the [[SPARTAN-III Program|Spartan-IIIs]] utilizes photo-reactive panels to conceal the wearer's infrared signature and to blend in with the surrounding environment. When combined with their natural talent and training for stealth, it can be a very effective tool. Some [[Headhunters]] used a prototype camouflage almost identical to the Covenant version, rendering them almost invisible, except that it only lasted 3-5 minutes and other systems have their power drained while it recharged. This feature saw very limited use in field tests by [[Orbital Drop Shock Trooper|ODSTs]].<ref>'''[[Halo: Evolutions - Essential Tales of the Halo Universe]]''', ''[[Headhunters]]''</ref> | |||

A common human active camouflage device, copied from similar Covenant technology, comes in the form of a "plug" which attaches to a socket located on the lower back of compatible armor. The non-integral nature of the device allows it to be added or removed at will for improved operational flexibility. The device provides a conditionally effective cloak; as long as the user remains still or moves slowly, the camouflage will be highly efficient, providing near-total invisibility for minimal energy loss. However, if the user moves more quickly, the camouflage will only provide rudimentary coverage and drain its energy very rapidly. Firing a weapon will also disrupt the camouflage and reveal the user. Furthermore, external sounds will be highly muffled to the user while this camouflage is in use, and if the user is equipped with motion tracking equipment, the detection capability of the motion tracker will be severely compromised, jamming the display with "ghost" targets.<ref>'''[[Halo: Reach]]'''</ref> | A common human active camouflage device, copied from similar Covenant technology, comes in the form of a "plug" which attaches to a socket located on the lower back of compatible armor.

This advantage is removed in ''Halo 2'' -- the Elites now wait, only activating their swords when they're about to kill the player. | ||

The Active Camo in ''[[Halo: Reach]]'' has undergone many major changes. It is now available as an [[Armor abilities|Armor Ability]] to both Spartan and Elite players. As a secondary effect, when used, it acts as a Radar Jammer, scrambling the radar of the user and all enemies within 25 meters, making the user harder for enemies to detect on their motion trackers. This function can be both beneficial and detrimental to the player; on the one hand, it can make enemies easier to ambush, however, it also informs the enemy team that someone is using Camo nearby. This can backfire on the player by making the enemy team more perceptive to possible ambushes. The Active Camo also greatly reduces the volume of all sounds for its user, making it more difficult to notice a grenade being thrown or a nearby enemy firing a weapon. | The Active Camo in ''[[Halo: Reach]]'' has undergone many major changes.

The strength or effectiveness of the Camo also varies depending on whether/how fast the user is moving. When standing still, the player is rendered almost completely invisible. Moving slowly or crouch-walking will slightly decrease the quality of cloaking, although the user is still hard to spot. When moving faster than crouch-walking speed, the Active Camo becomes much less effective, cloaking the user only partially (similar to the Poor Camo from Halo 3). The player's movement speed does not affect the rate at which the Armor Ability meter drains. | The strength or effectiveness of the Camo also varies depending on whether/how fast the user is moving.
