Behind the scenesEdit

  • The Division's slogan, "Exitus Acta Probat", translates from Latin to "the end justifies the means."
  • The Ballistic Defense Division's real-life equivalent is either United States Strategic Command, formerly Strategic Air Command, or Global Strike Command, one of USSTRATCOM's subordinate units, which have command and control over the US Air Force's 400+ intercontinental ballistic missiles.
  • General Martin Retslaf, commander of the silos located in the areas of Ashton and Hopeville, is specified as having been an officer in the U.S. Army, implying that the Ballistic Defense Division was an Army unit, rather than Air Force.
