Reapers are the most hardened terran criminals, taken from the most dangerous and violent prisons. Potential marines [...] who prove too intractable even after resocialization are instead sent to the "Icehouse" in the Torus system, where reapers are trained.Reaper troopers are chemically altered to make them even more aggressive before being subjected to weeks of brutal training in close-quarters combat and the use of their jet packs.

As well as other infantry, Reapers can be equipped with stimpacks [...][1].
