Born to a English mother and Belgian father, Kyle's junior years were stable. His father, a Belgian Army officer, spent most of his career serving in various UN peacekeeping forces abroad, most notably being the failed mission in Rwanda in 1994. As a platoon commander, he had the responsibility of keeping the president's wife safe from harm, yet she was killed by a Hutu militia and 10 of his men butchered in the process. The man never recovered from the incident, and throughout Kyle's adolecent years he had a father struggling with PTSD. This affected home a lot, with the relationship between his mother and father being severely affected due to her unwillingness to empathise with the illness.
This struggle took a toll on school. Not wanting to open up to anyone, he never truely faced his home issues head on and this lead to his grades slipping considerably, despite Kyle being a very bright kid. His main outlet was rugby. Although he never applied himself enough to chase any dream of professional play, it was Kyle's way of getting rid of all the anger, stress and agression that he built up. When he turned 18, he turned his attention to the military.
Although it had always been a consideration for Kyle, the military wasn't something he'd wanted to do his whole life. As he approached adulthood however, this changed. Due to the mission in Rwanda being a failure, Kyle's father always felt as though the family's name was tarnished, but pride prevented Kyle from letting this stay as the case. He thought it his duty, not only to his family, but to himself to right the wrongs of his father.
A few years later and Kyle had established himself as a model soldier. For his merits, as well as already being bilingual, he was given the opportunity to attend language school in Shrivenham and train in Russian.
