As a cargo transport, the S-2 is simple and utilitarian in design. Powered by propane, it is used for lifting and transporting crates and boxes that are too heavy to transport by hand. Throughout Halo 3, however, it was never seen doing its duty, as its civilian operators had either evacuated or were killed by the Covenant.
Along with other civilian vehicles, the forklift was made drivable by the player in Halo: Reach. Although forklifts travel relatively slowly, at its top speed it is capable of splattering a Sangheili General. Its speed, coupled with a lack of any defensive capabilities, makes the vehicle practically useless in gameplay. It is, however, extremely explosive, and when positioned properly, can act as an improvised explosive device within the campaign as well as firefight. The forklift in Halo: Reach originally had the ability to raise and lower its tines, but it was cut (rather ironically) due to being "crazy and pointless".
A drivable forklift appears in every campaign level in Halo: Reach.
It appears in only one firefight map in Halo: Reach: Courtyard.
Interestingly, the Forklift in Halo: Reach bears the GUNGNIR symbol.
Strangely, in Halo: Reach, if one explodes after being shot by a player and kills enemies, it will count the kills as splatters
Players as Sangheili in firefight are able to drive these as well; they cannot be hijacked, though.
Forklifts can be used effectively as a moble explosive. A useful tactic is to position a forklift in a chokepoint with an unexploded grenade from a grenade launcher beneath it and wait until an enemy player walks within range.
