Critical Assignment Arms were an optional set of replacement bionic arms for the Steve Austin action figure. Included were:
- a "laser" arm which contained a violet flashlight activated by pulling back the hand
- a karate chop arm with accessory pistol that would spring downward at the elbow
- an oxygen tank arm complete with mask and hose concealed in an internal compartment with door
All of the arms had a latex skin that could be, and in some cases had to be, rolled back in order to access or "repair" removable components contained within the body of the arm.
- Though obviously marketed as a part of the television franchise, in fact the arms owe their existence more precisely to the Martin Caidin Cyborg novels. To a much greater degree than was ever depicted on screen, the literary Steve Austin tended to have mission-specific bionic features in each new adventure.
