This book contains the complete unit rosters of the 4th Marine Division for January 1945. The information is organized by unit and last name. The data was compiled from the National Archives January 1945 Muster Roll, making this book perfect for Iwo Jima related studies.Every effort has been made to ensure the best possible accuracy. Please note that members of some Joint Assault Signal Companies (JASCO) may not be included in this book as they were assigned "as needed" to Marine Divisions and the division information was not always included in the muster rolls.The Spearhead - The World War II History of the 5th Marine Division is a publication that contains the complete unit rosters for the 5th Marine Division from 1943 through 1945. Although there are similar publications for the 3rd and 4th Marine Divisions, neither of these books contains complete unit rosters from any year. Please check out my other USMC Unit Roster books.
