Oleoresin Capsicum (OC) Spray or Pepper Spray. If the non-lethal weapons instructor-trainer is old-
school, they'll give you the "double-dragon" treatment on a windy day with an MK-9 or "
Mark Nine," which is the fogger version of the standard MK-4 they issue 5811s and 31Bs in AIT at Fort Leonard Wood Basic Military
Police Schoolhouse.
I hated being sprayed with the Devil's Piss, especially when I went through the MARDET FLW Basic MP Schoolhouse for INIWIC also referred to as the "House of
Pain". When GySgt. Sheaffer busted out the MK-9s I freaked out, but
hell, it was a windy day and he didn't wanna have to re-spray us with the "double-
dragon" treatment. Well, at least I earned and retained by Level II certification as a non-lethal weapons instructor.
