The Mercyhurst College Institute for Intelligence Studies (MCIIS) has developed a style manual for analysts to assist student analysts with the many perplexing and complex rules to follow when producing written intelligence products.The MCIIS Press developed this manual in large part from the CIA Writing Manual, updating some sections and modifying some others. This manual also draws on the U.S. Army’s Military Writing Reference Book for additional rules and guidelines regarding clear, concise writing. The final component in this manual, the MCIIS Style Sheet, reflects best practices in formatting a written product, as determined by MCIIS research.
