I voted for "Other", as I'd like to throw in Halo: Fleet Battles.
Essentially, it makes smaller ships harder to kill at long range, and makes larger ships more survivable at long range. Only Covenant ships carry the Cloak loadout (both small-class ships and one large-class ship), so it helps protect them from those infamous long-range UNSC MAC salvos.The Firepower Rating is reduced by one against any element with the "Cloak" system loadout in H:FB when firing at long range. This can have the effect of changing your dice from "exploding" to "heavy" (to use a DW/FA analogy), but it also stacks with other Firepower Rating modifiers and could make the shot impossible.
For instance: Covenant SDV heavy corvettes have both the Cloak and Hard Target system loadouts (Hard Target is analogous to the "Small Target" MAR in DW), which means capital-class elements are reduced by two Firepower Ratings against SDV elements at long range. UNSC MACs start at Firepower 4 at long range, meaning you can re-roll one Miss result for each "2" result on the attack dice. With Cloak and Hard Target, the MACs are reduced to Firepower 2, meaning all numbered attack dice results count as one hit, and there are no re-rolls. If a capital element targets an SDV that is at long range and behind an asteroid field, it drops to Firepower 1--no possible firing solution.
