As a specialized structure of the ICRC, the Advisory Service assists States to implement IHL at the national level. With a global network of legal advisers, the Service provides guidance to national authorities on specific domestic implementation measures needed to meet their IHL obligations, and it supports the work of national IHL bodies established to facilitate IHL implementation domestically. Moreover, the Service supports the exchange of information on national measures of implementation. Besides providing legal advice and technical support, the Service helps in capacity building, upon specific request of national authorities and other concerned actors.
