This rocket is a standard 2.75-inch air-to-air Mighty Mouse converted into a riot control rocket. In place of the usual explosive warhead is a head containing a smoke producing chemical, which was mildly irritating, but not lethal or noxious. This is a practice round. It is not known if riot control rockets were every used in a real world scenario.
Transferred to NASM from the U.S. Army Ordnance Museum.
