Expected a type of discount to make the list, though.
Thinking it might be hair for Farrah, not hear.
A Force Field is what keeps a ship in one piece when hull is broken, or what allows containment of a certain section, place, person or alien lifeforms. The exterior defence against energy weapons or torpedoes is not usually called Force Field, although I cannot say for sure it is never used in such context.
But its purpose is to absorb "Energy" and not block kinematic forces as a blind stopper which is the thematic Force Field in classic scyfy.
However you can redeem yourself in other alliterations by including "Deflector Dish" or "Will Wheaton" or "Admiral Akbar" (joke)
