not sure if someone may have already suggested this but.....
maybe delete the emperor's "....an entire legion of my best troops await them"
its not necessary and makes his "best legion" appear to be really rubbish against Ewok Ambushes....
or cunningly edit him to say:
"an entire legion of my worst troops await them.... just so it doesnt look like the Big dish that provides the impenetrable shield for my half-built, planet size, weapon of mass destruction isnt completely defenceless."
- and its a long sentance, just like what George Lucas would write.
