RAC

Radiologically Animated Corpse. RACs (pronounced "wracks") are dead or near-dead organisms that have had their biological functions extended by the incorporation of radiosynthesizing bacteria into the musculature. Although the original animal is clinically dead, the body remains active and is capable of performing instinctively ingrained behaviors as if alive, somewhat similar to a dead frog being made to move when it's muscles are electrically stimulated. As cellular function has ceased, RACs cannot heal from damage, resulting in RACs sporting horribly degraded forms caught in mid-decay, preserved by the environment produced by the peculiar conditions on the subcontinent following the 2014 invasion and kept animated by the heavy ambient nuclear radiation.
Despite their disturbing appearance, they are not especially dangerous to a trained combatant. They lack all but the most rudimentary and instinctual cognitive function and move quite slowly, with a stumbling, ponderous gait. They have a tendency to let out low moans when moving and will always take the most direct route to their target. They will usually attack something in an attempt to kill and eat it, but as RACs cannot starve this is purely an instinctual action. Similarly, RACs are capable of acting in self-defense and responding to physical harm. However, they do not feel pain and, as their organs are no longer essential to the body's continued operations, can be extremely difficult to put down for good. RACs can continue to act indefinitely even with their heads removed and the brain destroyed, though the lack of sensory organs will of course severely limit a RAC'S threat capabilities. Limbs separated from the body will continue to move leading to a number of horror stories from NLA soldiers of hordes of arms crawling through the wastes like caterpillars, searching for something living to grasp on to.
The bacteria responsible for this phenomenon is transferrable to any mammal creature via bite or the ingestion of infected body fluids. Infection is known to cause the subject to be attracted to high sources of radiation, which may cause a disregard for safety procedures and result in the subject's death due to radiation poisoning. Once the subject expires, the corpse will continue to move about. Due to RACs being highly resistant to damage, the best course of action regarding corpse disposal is cremation. This is standard procedure for deaths in the Subcontinental Exclusion Zone, where any fresh corpse can become infected. 
The Mogui created by the Black Dragon Bandits are believed to have been be a type of RAC, or somehow related given their resilience.
