Originally designed for clearing vegetation in agricultural settings and for signaling purposes, this ammunition has seen limited military applications. The primary tactical benefit lies in its psychological impact and limited area denial capability. Historically, reports suggest some use during the Vietnam War for these purposes, but widespread adoption has been hindered by safety and effectiveness concerns.
