Assistant Secretary of Defense for Special Operations and Low-Intensity Conflict
# Assistant Secretary of Defense for Special Operations and Low-Intensity Conflict

The Assistant Secretary of Defense for Special Operations/Low-Intensity Conflict or ASD(SO/LIC), is the principal civilian advisor to the U.S. Secretary of Defense on special operations and low-intensity conflict matters. Located within the Office of the Under Secretary of Defense for Policy (USD(P)), the ASD(SO/LIC) is responsible primarily for the overall supervision (to include oversight of policy and resources) of special operations and low-intensity conflict activities. These activities, according to USSOCOM's 2007 Posture Statement, include counterterrorism; unconventional warfare; direct action; special reconnaissance; foreign internal defense; civil affairs, information operations, psychological operations, and counterproliferation of WMD.

In addition to policy oversight for special operations and stability operations capabilities, the ASD(SO/LIC) has policy oversight for strategic capabilities and force transformation and resources. This includes oversight of capability development to include general-purpose forces, space and information capabilities, nuclear and conventional strike capabilities, and missile defense. As such, ASD(SO/LIC), after the Secretary and Deputy Secretary, will be the principal official charged with oversight over all warfighting capabilities within the senior management of the Department of Defense. The ASD(SO/LIC) is considered part of the Office of the Secretary of Defense.

## Structure

This position was mandated by the National Defense Authorization Act for Fiscal Year 1987 (P.L. 99-661, passed 14 November 1986). The position was officially established on 4 January 1988, by Defense Directive 5138.3. The post's responsibilities for strategic capabilities and forces transformation were added as a result of USD(P) Eric Edelman's 2006 reorganization of the DoD policy office.

The ASD(SO/LIC) is supported in his/her work by three Deputy Assistant Secretaries of Defense:

* DASD, Special Operations and Combating Terrorism
* DASD, Partnership Strategy and Stability Operations
* DASD, Counternarcotics and Global Threats

In November 2020, Acting Secretary of Defense Christopher Miller announced that Christopher Maier, director of the wide ranging DoD Defeat-ISIS Task Force had resigned, and that the task-force director’s duties and responsibilities will be absorbed by the Office of the ASD (SO/LIC) and regional staffs of the Office of the Under Secretary of Defense for Policy.
