A new frontier of defense for our country is the threat of Nuclear, Biological and Chemical (NBC) weapons and Weapons of Mass Destruction (WMD).

Chemical Officers also employ Chemical units in combat support with chemical, smoke and flame weapons, technology and management.

The responsibilities of a Chemical Lieutenant may include:

  • Commanding and controlling Chemical operations and combined armed forces during combat and peacetime.
  • Coordinating employment of Chemical Soldiers at all levels of command, from platoon to battalion and higher, in U.S. and multi-national operations.

Helpful Skills:

Being a leader in the Army requires certain qualities. A leader exhibits self-discipline, initiative, confidence and intelligence. They are physically fit and can perform under physical and mental pressures. Leaders make decisions quickly, always focusing on completing the mission successfully, and show respect for their subordinates and other military officers. Leaders lead from the front and adjust to environments that are always changing. They are judged by their ability to make decisions on their own and bear ultimate moral responsibility for those decisions.

Advanced Responsibilities:

Chemical Officers may continue in the Operations career field, serving in Chemical Corps at ever increasing levels of leadership and responsibility.
