designated part of the Selected Reserve Force, higher priority Reserve Component units that received better equipment and greater funding in order to maintain higher levels of readiness. In 1981, elements of the 38th Infantry Division took part in Exercise REFORGER (Return of Forces to Germany) as a way of testing the United States' ability to strategically deploy reserves into West Germany in response to a Warsaw Pact invasion. Other elements of the 38th Infantry Division, both company sized units as well as individual Soldiers, have participated in Overseas Deployment for Training missions in Germany, the United Kingdom, Republic of Korea, Japan, and in Central America. With the exception of Company D (Ranger), 151st Infantry, elements of the 38th Infantry Division were not activated for federal service in combat operations from 1945 until Operation Desert Storm in 1990. However, elements of the Division were frequently called up for State Active Duty to support civil authorities in mitigating the effects of natural disasters and civil unrest. Two of the largest callups were for the Perfect Circle strike of 1955 and the Palm Sunday tornado outbreak of April 1965. Company D (Ranger), 151st Infantry was the sole divisional element (and one of a small number of National Guard units) mobilized for service in the Republic of Vietnam and was one of the most highly decorated units to serve in that conflict. In 1996, over 7,000 soldiers from the 38th Infantry Division (from Indiana, Ohio, and Michigan) supported the Centennial Olympic Games in Atlanta, Georgia. In 1998, Echo Battery (Target Acquisition) 139th Field Artillery deployed to Bosnia as part of peacekeeping operations in the former Yugoslavia. Also in 1998 the 76th Infantry Brigade (Separate) was selected to participate in a training deployment in the summer of 2000 to the Joint Readiness Training Center (JRTC) at Fort Polk, LA. The 38th Division Support Command (DISCOM) supported the JRTC rotation by operating the logistics support area (LSA), while many units within the division provided equipment and manpower to support the 76th Brigade. The equipment deployment from Indiana to JRTC was via river barge, among the largest moves of equipment for Indiana units since World War II. Post 9/11 Mobilizations Since 11 September 2001, the 38th Infantry Division has provided headquarters and forces for a variety of operational rotations including Operation Iraqi Freedom (Iraq), Operation Enduring Freedom (Afghanistan and Cuba), Operation Joint Forge (Bosnia), Operation Joint Guardian
