In continuous action as a front line regiment for a total of fifty-two consecutive days, the gallant men and officers of the THIRD Marines, by their skill in jungle warfare and their aggressive fighting spirit, contributed greatly to the success of the campaign and enhanced the highest traditions of the United States Naval Service."
