The Combat Studies Institute has published its follow on operational history report looking at the US Army in Operation Iraqi Freedom (OIF).

“On Point II is a comprehensive study of the US Army in Operation IRAQI FREEDOM (OIF) from May 2003 to January 2005. Based on primary sources including hundreds of interviews with participants, the study examines how after May 2003 American Soldiers made the transition to a new type of campaign that featured information operations, intelligence, reconstruction, and governance rather than conventional combat. On Point II documents the US Army’s execution of Full Spectrum Operations in the early stages of this conflict.”

“On Point is a study of Operation IRAQI FREEDOM (OIF) as soon after the fact as feasible. The Army leadership chartered this effort in a message to the major commands on 30 April 2003. In his guidance, Army Chief of Staff General Eric K. Shinseki directed "a quick, thorough review that looks at the US Army's performance, assesses the role it played in the joint and coalition team, and captures the strategic, operational, and tactical lessons that should be disseminated and applied in future fights." The authors worked rapidly and diligently to capture the essential lessons of the campaign; as a result, the study is available today to help leaders at every level.”
