SOLLIMS Sampler - Strategic Lessons In Peacekeeping and Stability Operations. Prior to the SOLLIMS Sampler there was the Strategic Lessons Sampler. This was the first issue. This publication is designed to provide senior leaders and their staffs with key lessons – at the strategic level – from recently conducted peacekeeping and stability operations (P/SO). These lessons have applications for the U.S. Army, the Department of Defense (DoD), and numerous other U.S. Government departments and agencies – including the Department of State, the Department of Justice, the Department of Agriculture, and the U.S. Agency for International Development (USAID).
