"The truths about the Fallen chain-of-command are still making themselves known, but Vandals appear to hold a higher ranking than the Dregs, and deadlier weapons, too. They often have long range capability, but, lucky for us, their weapons take time to charge."
- - Bungie Description
Vandals are higher ranking in the Fallen army than Dregs but are subordinate to the Captains. They use weapons capabile of firing long ranges and with more power, the downfall of these weapons however is the requirement for a long recharge period.
