I would prefer to believe they are more dangerous with full armour on.... Actually this is the only moment where a stormtrooper is remotely dangerous yet we don't see anything and it does not sound like a stormtrooper.

But C3PO tells us when chewie repairs him

Thinking about it..... Is there actually any storm trooper lines in empire?

It is something that seperates it quite a lot from star wars a new hope where troopers although faceless I miss that sound of the stormtroopers dialogue... If some could be added I think it might work very well especially cloud city and hoth... Although not in excess more of a token effort than trying to add in dialogue that simply does not exist but it is something missing with empire.

When i say token dialogue... Without feeling cheap but the audio was actually the only factor that made storm troopers characters to add a "sir" or "blast them" might be enough at least to connect the dots to their previous incarnation.

A small touch but a big difference it would be
