Whoa dudes!! Lets take a deep breath. Just to be clear, Im not rying to poke a hole in the Star Wars canon here. A thought just popped into my head while I was working and it got me to thinking. Thanks for all the answers though.

We know Bail O. uses the Tantive 4, or same model of ship, in the OT. So it stands to reason this was indeed Leias ship, with Leias troops/guards/etc. The Tantive was how she travelled back and forth to work. Assuming that, then the gray/black guys were indeed Alderaanians. Apparently, the political leanings of Alderaans leaders heavily influenced their people, hence the large contingency of similarly dressed troops in the final ceremony of ANH. All Im trying to establish is a long held believe from childhood is that if you wore grey and black with the funny helmet, you were a rebel. Well, thats just not true based on the events of R1 and ANH. Kind of like the “not all muslims are terrorists, but all terrorists are muslims” adage.
