I am researching WWII USMC squad-level tactics, in particular, the use of fire-teams. As part of my research I came accross the name of Colonel (Ret.) Martin Sexton of 6th Marine Division. I would like to contact him to learn more about Marine squad tactics. Would anyone be able to help me contact him? Also, is there anyone else I could contact to get further, first-hand knowledge of WWII Marine tactics? Thank you in advance for any help you can provide.
