The Law of Armed Conflict and Military Operations (LACMO) is an autonomous research group within the Amsterdam Center for International Law that investigates the role of law, in particular public international law, in relation to a wide variety of military operations and security challenges.

The cooperation with other universities and defence colleges is organised around a newly established research consortium operating under the name of ‘LACMO Research Network’. The research network is based upon a framework agreement for organizing joint projects, conducting cooperative research, joint supervision of PhD projects and exchange of personnel. The LACMO network currently comprises around 20 research groups from as many universities and military staff colleges and academies in Europe, North America and Asia and the Pacific region.
