The contribution of members of Phi Delta Theta in the military is arguably the most distinguished and highly decorated of any fraternity. For over 160 years, members of Phi Delta Theta have fought with distinction on the battlefield. Phis have participated in every major conflict from the Mexican-American War to the current war against terrorism. Many others have served ably in high civilian leadership positions on the homefront. Tens of thousands from every chapter have fought in every branch of the military both in the United States and in Canada. As a testament to their courage, over 1,100 Phis have sacrificed their lives for the cause of Freedom.
