The Terrans at first don't like using shock jump tactics because it was probably considered a suicide, and most Terran ships are designed for broadside engagements. Unless the ship performing it is a Lucifer or Sathanas, most Shivan ships usually get destroyed after doing a shock jump. In FS1, only the Lucifer is seen doing it. In BP, they started adding it as a possible strategy probably because they can sufficiently defend the ships, as well as having better jump drives and better AWACS to calculate precise coordinates and thus ensuring the ships can do as much damage as possible to the enemy and getting out in one piece.
