Do you envision Captain Kirk shooting photon torpedoes at Klingons? What exactly is a photon torpedo?
But what would it look like if it happened today? Actually, it would probably not be so visual. You can take out a satellite with jammers and spoofers. Messing with the enemies IC4 (intelligence, command, control, communications and computers), can easily cripple his earthly forces.
Or it can massively disrupt commercial activities and crash the enemy’s economy. This is brutal stuff.
