In 'Under Siege' (1992) Ryback has to prevent a group of military mercenaries led by ex-CIA operative Bill Strannix and his Executive Officer Commander Krill (Tommy Lee Jones and Gary Busey) from hijacking the battleship USS Missouri and stealing its store of nuclear weapons. 'Under Siege 2 - Dark Territory' (1995) sees the newly-retired Ryback attempting to prevent a team of terrorists on a hijacked passenger train from using a weapons satellite to destroy Washington D.C..
