Due to the radically skewed population and wealth distribution on Earth Jack Cooper's family relocated to the Frontier in search of a better life when he was an infant. The rural Frontier community they inhabited was subjected to harassment and exploitation by IMC garrisons. As the IMC continued to disrupt the livelihoods of the people in his home system, Cooper volunteered as a Militia Rifleman 3rd Class to free the Frontier from the oppression of the IMC. One of his first assignments as a rifleman was during the battle of Fracture, where he suffered a head injury in the line of duty and had trouble remembering his involvement as a result.

- Although his ethnicity is assumed to be Caucasian, in the Art of Titanfall 2 book, Lead Artist Joel Emslie said of his appearance, "We went for the look of a guy who might be a mix of ethnicities with a hint of Benecio Del Toro."
- He was present at Operation: Fracture, and suffered a concussion that led to a minor case of amnesia.
