HHD 2nd chemical batalion

Headquarters and Headquarters Detachment, 2nd Chemical Battalion, traces its origins to its activation in 1917 during World War I as the 30th Engineer Regiment (Gas and Flame), which specialized in chemical warfare. The unit was reorganized and redesignated as the 2nd Chemical Battalion in 1940, serving with distinction in World War II, including campaigns in North Africa, Italy, and France. Throughout the Cold War and into the 21st century, the battalion has provided vital chemical, biological, radiological, and nuclear (CBRN) defense capabilities to the U.S. Army. Today, HHD, 2nd Chemical Battalion remains at the forefront of CBRN defense, supporting both domestic and overseas operations to safeguard troops and civilians from weapons of mass destruction.
