Gender...perspectives need to be considered in all areas of peace and stability operations. Acknowledging this reality, in October 2000 the UN Security Council adopted Resolution 1325 on women, peace and security. Since then, it has become widely acknowledged that involving both men and women in peace-building efforts...is essential. Still, women’s views are often side-lined in security institutions and SSR processes. Although many clients of private military and security companies (PMSCs)...have mainstreamed gender concerns into their peace support operations and post-conflict reconstruction projects, PMSCs are only beginning to do so. This article considers the importance of integrating gender perspectives into PMSCs and identifies practical ways to do so.
