Civil-military operations (CMO)


Civil-military operations (CMO) refer to activities and interactions between military forces and civilian authorities, organizations, or populations. These operations aim to establish or maintain a safe and secure environment, support humanitarian objectives, or facilitate conflict resolution. CMO often includes cooperation, coordination, and communication between military and civilian entities in areas such as reconstruction, infrastructure development, and disaster relief.

Key Takeaways

  1. Civil-military operations (CMO) are activities designed to establish, maintain, influence, or exploit relations between military forces, the civilian population, and local government institutions to support the overall mission.
  2. CMO serves as a tool for promoting cooperation, resolving conflicts and fostering a secure environment to achieve strategic military objectives, while also addressing the needs of the civilian population and ensuring the efficient use of resources.
  3. Key components of CMO may include civil affairs, humanitarian assistance, psychological operations, and coordinating with non-governmental organizations, international governing bodies, and local civilian leaders to build social, political, and economic stability in the region.


Civil-military operations (CMO) are a critical aspect of military operations, as they facilitate effective collaboration, communication, and coordination between military forces and civil authorities in complex environments.

CMO fosters greater understanding and cooperation to achieve common objectives and support the overall mission.

By integrating military efforts with those of local institutions, governmental and non-governmental organizations, CMO helps to restore essential services, build public trust, and ensure the long-term stability and development of the affected areas.

Moreover, CMO focuses on mitigating the impacts of military operations on civilian populations, ultimately contributing to a more comprehensive and holistic approach to conflict resolution and post-conflict reconstruction.


Civil-military operations (CMO) are designed to reinforce and uphold the strategic objectives of a military campaign while prioritizing the welfare and needs of affected civilian populations. This vital aspect of military operations is aimed at fostering collaboration between military forces, civilian authorities, and local communities.

The primary purpose of CMO is to establish a support network that strengthens ties between these groups, thereby bolstering the efficacy of military endeavors and ensuring that civilian life remains as stable as possible. In essence, CMO recognizes the importance of human security during conflicts and aims to maintain the trust and cooperation of civilians in conflict-prone areas.

By delivering humanitarian assistance, engaging in reconstruction efforts, and facilitating dialogue between armed forces and community leaders, CMO bridges the gap between military forces and the civilian population. These efforts not only contribute to the overall stability and resilience of communities, but also serve to balance the potentially negative consequences of military operations on civilian livelihood.

Moreover, CMO initiatives help create an environment conducive to the success and eventual conclusion of conflict, laying the groundwork for long-lasting peace. Through such engagements, military forces are better able to promote goodwill, minimize collateral damage, and undermine the influence of adversarial factions in contested regions.

Examples of Civil-military operations (CMO)

Operation Unified Assistance (2004 Indian Ocean Tsunami): In December 2004, a massive earthquake triggered a devastating tsunami across the Indian Ocean, which resulted in the deaths of over 230,000 people and widespread destruction in 14 countries. In response, the US military, alongside other foreign military forces, humanitarian organizations, and local authorities, conducted civil-military operations under Operation Unified Assistance. The joint effort provided emergency relief, medical assistance, transportation, and logistics support to facilitate the distribution of aid and assistance to the affected areas.

Operation Restore Hope (Somalia, 1992-1993): The United Nations Operation in Somalia (UNOSOM) was an example of a civil-military operation involving a coalition of military forces from various countries working alongside humanitarian organizations. This operation aimed to provide humanitarian relief and security to the people of Somalia, who were suffering from widespread famine, civil war, and lawlessness. The military forces helped distribute food and other supplies, protect aid workers, and provide a secure environment for humanitarian assistance. Additionally, they assisted in rebuilding infrastructure and facilitating the return of displaced persons to their homes.

Operation Tomodachi (Japan, 2011): Following the Tohoku earthquake and tsunami in Japan in 2011, which caused significant damage to coastal regions and triggered the Fukushima Daiichi nuclear disaster, the US military launched Operation Tomodachi in support of Japanese Self-Defense Force’s relief efforts. This civil-military operation included search and rescue missions, medical support, logistical assistance, and the distribution of humanitarian aid. The operation also involved efforts to mitigate the nuclear crisis by providing specialized equipment and expertise to prevent further radiological releases.
