Bradley Vaughton was a veteran of the First Vektan War and was a friend of ISA soldier Dirk Templar. After Dirk died in the war, Vaughton felt responsible to look after Dirk's son Jan Templar, whom he sees him as his godson.
Vaughton ordered Jan Templar to meet up with Shadow Marshal Luger and Rico Velasquez in order to complete a mission to rescue Colonel Gregor Hakha. Before Templar went on the rescue mission he retrieved the security key for General Vaughton who then went up to the SD Platform to reactivate the platform's weapon systems.
Vaughton had respect and trust from his troops due to his professional nature and high moral fiber, most notable of these troops was Jan Templar.
Training him with all the required military skills to exceed his father's potential, Templar matured into a deeply promising soldier, far more intelligent tactically and morally unwavering than other ISA soldiers. This forged a strong father-son bond between the pair illustrated during the events of Killzone where Vaughton entrusted Templar to guide a small unit through Vekta, triggering a famous fight from Templar.
Unlike the traitors such as Stuart Adams or Dwight Stratson, and even the loyal but morally dubious Alex Grey, Vaughton showed no moral failings and likely would've continued to serve as one of Vekta's greatest generals, if he had not been killed.
- Vaughton bears a striking resemblance to Supreme Allied Commander Dwight D. Eisenhower.
