I like to think that stormtrooper armour is far more effective than the films let on. Thus, in my mind’s eye, this is what happens to almost every stormtrooper who gets shot in the OT:
“Dead or alive, you’re coming with us!”
“Eat red-hot plasma, buckethead!”
*wilhelm scream*
…
“Good thing my armour absorbed the brunt of that blast. Otherwise that shot would have killed me instead of momentarily knocking me unconscious. Now that I have my wits about me, I can continue my relentless pursuit of the Rebel scum.”
