# Second Investigation Department

The Second Investigation Department or AOTD (Lithuanian: Antrasis operatyvinių tarnybų departamentas) is a Lithuanian intelligence agency under the Ministry of National Defence. It conducts military intelligence as well as intelligence and counterintelligence in the areas of defense.

## History

The origins of the institution are in the Intelligence Unit established within the Lithuanian Armed Forces on 27 October 1918. In 1923, many intelligence activities were transferred to the Ministry of the Interior forming what later became the State Security Department of Lithuania. Military and defense related intelligence stayed within the General Staff and after 1929 the service was reorganized and named the Second Unit.
After Lithuania regained independence in 1990, the department was reestablished as the Information Unit, later reorganized and renamed to the Second Investigation Department in 1997. Its early task was to gather intelligence on Soviet military units operating in the region. Since Lithuania became a member of NATO, AOTD has cooperated closely with the NATO intelligence community.
