464th Chemical Brigade (United States)

The 464th Chemical Brigade was a chemical unit in the United States Army Reserve from February 1972 until September 2008.

Mission To provide command and control of two to six chemical battalions and other assigned or attached separate companies at Corps level. To provide staff planning and coordination for the combat, combat support, and combat service support operations for all assigned and attached units. To allocate units and resources in support of chemical, biological, radiological, and nuclear (CBRN) reconnaissance, decontamination, biological detection, and smoke operations. And, to conduct civilian decontamination in response to a domestic accident or deliberate CBRN incident.

Motto We Serve In Silence is the motto of the 464th Chemical Brigade. This motto connotes the silent, but deadly force of the weapons that the chemical corps built to combat and the silent, dirty, thankless, yet life-saving job that the chemical soldier performs with the utmost expertise, dignity, and honor.
