> The M44s relatively small production numbers were due, like all U.S. BZ munitions, to a number of shortcomings. The M44 dispensed its agent in a cloud of white, particulate smoke.[3] This was especially problematic because the white smoke was easily visible and BZ exposure was simple to prevent; a few layers of cloth over the mouth and nose are sufficient.[5] There were a number of other factors that made BZ weapons unattractive to military planners.[5] BZ had a delayed and variable rate-of-action, as well as a less than ideal "envelope-of-action".[5] In addition, BZ casualties exhibited bizarre behavior, 50 to 80 percent had to be restrained to prevent self-injury during recovery.[5] Others exhibited distinct symptoms of paranoia and mania.[5]
