The Army's chemical, biological, radiological, and nuclear investigation teams discover information about an enemy target to defend the country from the threat of weapons CBRN and weapons of mass destruction. The military has evolved dramatically in terms of Chemical Corp. Today there are multiple units around the world operating in survey teams. The two most popular units in the Chemical Corp are the technical escort units and the chemical reconnaissance detachments. There is a lot of confusion about what the operations of these two units entail. This research paper will describe what they do and discuss the similarities and differences between the two. The primary mission of technical escort units is to prepare for rapid deployment with little or no warning anywhere in the world. They conduct technical escort missions immediately upon arrival. This means they must always be prepared and ready to go. The battalions conduct joint operations against many different CBRN, weapons of mass destruction (WMD), toxic industrial chemicals (TICs), and toxic industrial materials (TIMs) risks with military and civilians. (Technical Escort Battalion Operations, pages 1-1) Fort Leonard Wood Army Base in Missouri holds a four-week course that military personnel can attend to gain knowledge and become more successful in technical CBRN operations. (CBRN Tech Escort Course Comes to Fort Leonard Wood, http://www.army.mil/article/ 23052/CBRN_Tech_Escort_Course_comes) There are five different mission sets that the teams work on. They are emergency response, cleanup and restoration, technical stockpile of materials, technical chemical, biological, radiological and nuclear support to COCOMs and national security. Emergency response is one of the main tasks... middle of paper... much faster paced environment. The position required me to attend numerous military courses and I conducted actual live missions and gained important tactical skills from each experience. I would encourage any Army chemical operations specialist to join these units at some point in their career. This will benefit them in their careers and help them become well-rounded soldiers.
