Micron Products also specializes in defense components, like blunt impact projectiles. These less-lethal projectiles created for Security Devices International (SDI) are used by police and military groups worldwide, including the Israeli Army, the Los Angeles SWAT Team, and the Royal Canadian Mounted Police. Unlike traditional ammunition, these 40-millimeter projectiles do not penetrate skin, but hit a human target with enough force to cause pain without lasting injury.
