"There is no unit in the American Army which has served with greater distinction both in peace and in war, than the 31st Infantry… the Regiment has always performed its assigned  mission with marked gallantry and commendable precision… its lines held firm time and time again against the assault of overwhelming superior forces. As it now faces a future of continued service in our country’s cause, it’s regimental colors fly under a halo of tradition, of honor, duty and sacrifice, which will be an inspiration for American Armies for all time to come.”

-General Douglas MacArthur
August 4th, 1946
