Throughout its history, the Army Nurse Corps has evolved as a world-class center of excellence for military nursing and a bench mark for caring for the entire nursing community. Army nurses have remained at the forefront of change, providing leadership in integrating nursing research and nursing education into clinical practice. Today, we continue the legacy of a proud heritage by maintaining the highest standards of professionalism in nursing and in military service. Our professional evolution reflects not only the changing requirements of a progressive Army, but also our expanding roles in supporting the health care needs of our nation. While endeavoring to meet the contemporary challenges posed by changes in the military mission, organizational structures, technological advances, and increased services, we have kept our commitment to support the health care needs of the soldier, the family, and other beneficiaries. Our past has prepared us to meet the challenges of today and validates our potential for meeting the health care challenges of the future. The global nature of our mission provides Army nursing the unique opportunity to serve both country and humanity. These highlights of our past provide testimony to our heritage and our professional contributions to the Army Medical Department, the Army, and the nation.
