Captain

Unit:

Company B, 1st Battalion, 6th Marine Regiment, 2nd Marine Division "The Silent Second", U.S. Marine Corps

Citation:
"For extraordinary heroism as Commanding Officer of Company B, First Battalion, Sixth Marines, SECOND Marine Division, in action against enemy Japanese forces during the assault on Saipan, Marianas Islands, on 17 June 1944. When his company sector was undergoing a heavy attack by hostile tanks and supporting infantry, Captain Rollen remained cool and aggressive, although his company area was penetrated and overrun by the enemy and heavy casualties were sustained. As the tanks were approaching his Command Post Area at one stage of the action, he left his protected position and fired upon two tanks with antitank grenades and, although the resultant explosion broke his eardrums, continued to carry out his duties and control his company until ordered to be evacuated after the attack had been successfully repulsed. His outstanding courage, inspiring leadership and devotion to duty were in keeping with the highest traditions of the United States Naval Service."
