The Camp offers a variety of training ranges, live-fire venues, managed airspace with air-to-ground fighting capabilities and an LVC simulation and exercise center.

[6] The U.S. Army contracted John Richard Walsh as a real estate project manager to oversee the initial development at the camp that would accommodate and train a full-sized, triangular division of 40,000 soldiers.

An estimated 700 vehicles and daily bus service provided transportation from nearby towns and an on-site concession tent served meals to 600 workers at a time.

[12] The camp's training facilities also included twenty-one firing ranges and about thirty buildings arranged as a small town, nicknamed Tojoburg, to provide soldiers with field practice in a village setting.

Initial construction included forty-three, two-story buildings for patient wards, treatment facilities, mess halls, a post exchange, an auditorium, and a recreation center, as well as housing for medical officers, enlisted men, and nursing staff.

[15] In July 1944 the Women's Army Corps Medical Department Enlisted Technicians' School was relocated to Camp Atterbury from Hot Springs, Arkansas.

The wounded arrived by airplane from Atterbury Army Air Field (modern-day Columbus Municipal Airport), about twelve miles away, and by train on the Pennsylvania Railroad.

In addition to its staff, the hospital had the American Red Cross and a group of local women, known as the Gray Ladies, as volunteers to assist its patients.

The Red Cross and United Service Organizations also provided entertainment in the form of recreational activities, shows, and special events.

[23][24] Brigadier General Ernest A. Bixby succeeded Colonel Modisett as post commander in June 1945, when the camp was active as reception and separation center.

The division left Camp Atterbury in June 1943 for further training in Tennessee and Kentucky before shipping out to England and the European Theater of Operations in April 1944.

[29][30] The 365th Infantry Regiment and the 597th Field Artillery Battery, two units of the 92nd Division, under the command of Colonel Walter A. Elliott, were reactivated at Camp Atterbury on 15 October 1942.

[32] The 106th "Golden Lion" Division, under the command of Major General Alan W. Jones, arrived at Camp Atterbury in March 1944 and left on 9 October 1944.

[27][34] Another unit, the U.S. 39th Evacuation Hospital, under the command of Lieutenant Colonel Allen N. Bracher, was activated on 30 August 1942, and departed from Camp Atterbury on 7 June 1943, for Tennessee.

This all-black group of WACs performed duties at Wakeman Hospital as part of the 3561st Service Unit and cared for wounded soldiers returning from combat.

[43] Camp Atterbury's first wartime, all-soldiers radio show, called "It's Time For Taps," aired from Indianapolis on Thursday, 8 October 1942, at 1310 AM kHz.

[52] In 1943 Lieutenant Colonel John Gammel gave the Italian prisoners permission to erect a small chapel about 1 mile (1.6 km) from the internment compound.

[47][59] In August 1944 the reception (induction) center at Fort Benjamin Harrison, northeast of Indianapolis, was moved to Camp Atterbury, where it was organized as a separate unit in October 1944.

In addition to the inductees, about 3,000 military personnel who were awaiting reassignment passed through Camp Atterbury's reception station, organized as a separate unit in November 1944.

Military personnel arriving at the reception station usually stayed twelve to twenty-four hours before they were sent home or reassigned to other duties after a brief furlough.

[61] Shortly after Victory over Japan Day in August 1945, Brigadier General Ernest Aaron Bixby, the camp's commanding officer, announced that its huge receiving and separation centers (the U.S. Army's second-largest separation center during World War II) were discharging a daily average of 1,000 U.S. Army troops with sufficient points (85 points or more) or qualifying dependency.

[74] Since 2003 thousands of regular and reserve forces have trained at the camp prior to their deployment to Afghanistan, Iraq, Kosovo and other locations around the world.

[citation needed] In April 2010 plans were announced to reclaim an estimated 1,200 acres (4.9 km2) of land for construction of Indiana National Guard offices, barracks, and other facilities.

It offers a variety of training ranges, live-fire venues, managed airspace with air-to-ground firing capabilities and an LVC simulation and exercise center.

CAIN has secure facilities, simulations, ranges, configurable classrooms and conference spaces to provide users with experiences that are versatile and mission specific.

The facility combines a walking campus, new barracks complex and multiple life support features to units conducting large-scale training and pre-operational testing.

The facility has ample command post pads that are digitally connected to the simulations network infrastructure and can support multiple divisions and brigades simultaneously.

It is a real city that includes a built physical infrastructure, a well-integrated cyber-physical environment, an electromagnetic effects system and human elements.

As users regularly add role-players to create dense urban terrain (DUT), the unpredictable realism slows operations while increasing the speed and complexity of tactical engagements.

The Indiana Air Range Complex (IARC) enables training and testing activities utilizing special use and managed airspace supporting both kinetic and non-kinetic air-to-ground operations.
