Fort Jackson is a United States Army installation, which TRADOC operates on for Basic Combat Training (BCT), and is located within the city of Columbia, South Carolina.

Camp Jackson was reactivated for World War II, where Franklin D. Roosevelt and George C. Marshall hosted a demonstration of the combat-readiness of several divisions for Winston Churchill and Alan Brooke in preparation of the abandoned Operation Roundup.

While some military installations have experienced downsizing and closure in past years, Fort Jackson has added several new schools and training institutions since 1995, including the U.S. Army Soldier Support Institute, the Department of Defense Chaplain Center and School, and the National Center for Credibility Assessment, part of the Defense Intelligence Agency.

[10] Soldiers, civilians, retirees and family members make up the Fort Jackson community that continues to grow in numbers and facilities.

[8] An estimated 3,500 active duty personnel and their 12,000 military family members make the Fort Jackson area their home with about one-third of that total population residing on-post.

[11] Close to 3,500 civilians are employed at Fort Jackson and 46,000-plus retirees and their families receive services from this base.

Annual expenditures by Fort Jackson exceed $716.9 million for salaries, utilities, contracts and other services.

Brigadier General Milford Beagle, the installation commander for Fort Jackson, later put out a statement saying that Collazo did not possess any ammunition for the M4 he was carrying, but both the bus driver and children on board would not be aware of that.

Collazo is now facing multiple charges, including 19 federal counts of kidnapping, armed robbery, and carjacking.
