Small Unit Actions, eleventh in the series of monographs on American operations in World War II, marks a departure from earlier numbers in that series. It presents, instead of a coordinated treatment of a larger operation, four detailed narratives dealing with small units which took part in such operations. Each narrative has a unity of its own, but the actions dealt with are separate and distinct, relating to four campaigns in three main theaters of war. AMERICAN FORCES IN ACTION SERIES presents detailed accounts of particular combat operations of United States forces. To the American public, this record of high achievement by men who served their nation well is presented as a preface to the full military history of World War II. To the soldiers who took part in the operations concerned, these narratives will give the opportunity to see more clearly the results of orders which they obeyed, and of sacrifices which they and their comrades made, in performance of missions that find their meaning in the outcome of a larger plan of battle.
