So, I was watching TMP last week, and something really stuck out this time. The number of discrete defensive systems referenced in the various scenes is pretty considerable. Through the course of the film, we hear the following terminology: Deflectors Screens Shields Force Fields TOS had different systems referenced at times as well. By the time TWOK rolls out, however, we are generally just talking about "shields." Now, you could say that these are all referring to the same system, but the dialogue absolutely doesn't support that. Decker recommends "Screens and shields" at one point. Chekov yells about "forcefields and deflectors" both being up on full. Scotty says that the ship "Cannot maintain full power on forcefields" and then immediately after says "Deflector power is down 70%" All this seems to indicate different systems that work together to protect the ship. Thoughts?
