Panel two shows what looks like one stormtrooper, one long-haired "ninja", and one other; panel three shows that there is a second stormtrooper. Both show someone off to the side, on the right-hand edge of the panel. Panel four makes it look like that person has gone into the ship; there's no evidence of the watcher in panel five.

Remember when I said about, "I mean, how much of an idiot would the Empire have to be in order to let someone say that they're bringing large supplies of bombs and guns and just let them land like a normal cargo shuttle with no guard?"? Yeah, I think that's exactly what happened here. A small contingent of guards for a large amount of guns and bombs, they all go in, they all get ambushed, and no one is any wiser.

Can someone please explain to me how it took 20 years for a Rebellion to get rid of this Empire? If anything, I'm thinking the Rebellion is more incompetent than the Empire.

That goes right up there with the idea that people are trying to use Tatooine sandworms for an alternative space drive, or that hiding a child with their close relative is a good idea.

At the very least, they could have shot these guys while they were still on the ramp, while they still had the high ground. :-)
