Deployable lookout tower
From Halopedia, the Halo wiki
A deployable lookout tower is an anti-gravity-operated tower used by the Covenant. They are mainly used to fortify specific areas on a battlefield.
A deployable lookout tower is comprised of a circular base, in the middle of which an anti-gravity generator is placed. The circular platform is suspended in the air, given the anti-gravity power by the generator. The platform also has a gap in the middle through which the occupants are transported. The anti-gravity generator works just like a gravity lift, transporting supplies and troops freely. It also has the same color as the gravity lift.
The perimeter of the base is comprised of three ramps and three pillars, probably put there for extra protection. They are all placed in a motif (one ramp to one pillar). The platform has also three protective pillars and large gaps between them. The pillars are taller and thinner compared to the ones of the base and the gap between them is bigger. The gap is used for snipers to have a clear line of sight and for Gunner Unggoy to place their Type-52 plasma cannons. Some towers' platforms, instead of the usual oval pillars, have three thinner, longer pillars that support a rooftop-like cover. Earlier versions may also include an energy shield wall next to them, and will activate when the tower is occupied.
The base, when placed on the ground, can not be moved again. The platform, however, is not as steady as the base and a single shot from heavy weapons, such as the M41 rocket launcher, the Type-33 fuel rod gun from a distance and the M90 or M45 shotgun from nearby, will make it lose its balance and it may fall off. One shot from the rocket launcher is sure to make it fall.
In Halo 2, the platforms are indestructible. The player can climb on them by the anti-gravity lift, and can use it just like any Covenant. However, their position becomes highly exposed then. They appear in numerous campaign maps as well as in the multiplayer map, Relic.
In Halo 3, they are destructible. They are also able to be climbed and appear in some campaign levels.
In Halo Wars, they are deployed by the Covenant, but once every single Covenant troop on it is killed, UNSC soldiers can garrison in it, increasing their combat capabilities. A Covenant file is usually found on top of them defending the Kig-Yar and Unggoy Heavies there. In Skirmish, they are left neutral for either team's taking, providing a useful defense, if needed, plus they will not be destroyed no matter how many times a marine hits it. Certain maps, such as Tundra or Fort Deen, include lookout towers that are connected to energy walls. When garrisoned, the energy shield wall activates and prevents ground units from moving through. These walls can be bypassed by air units, Jiralhanae Jumpers, and occasionally Type-47B Scarabs.
In Halo: Reach, they are largely similar to those in Halo 3 with minor aesthetic upgrades.
In Halo 4, they are very similar to their Halo: Reach counterparts. However, the player must crouch to enter it due to narrower hole of entrance.
