Plot hole: Cato doesn't even know who Ord (the person she is impersonating) is, and yet she manages to perfectly imitate his voice and manner. She wouldn't have transformed her own internal organs, since she probably would have ruptured them.
Suggested correction: Quite apart from anything else, Cato is a member of a shapeshifting species, so why wouldn't she be able to perfectly take the form of another species? And her internal organs have nothing to do with the plot of this episode.
Plot hole: When Lawquane spots the droids in the field, he identifies them instantly as commando droids. But as he had left the Republic Army shortly after the first battle on Geonosis (the one which started the war) and has lived as a farmer ever since, and since the commando droids are relatively new (see "Rookies"), how can he know what they are? With his lack of battlefield experience, he should simply call them battle droids.
Suggested correction: Though the films and series downplay this, the Star Wars universe has its equivalent of an internet/tv channels via the Holonet, which is how most normal citizens get their news. Even a deserter-turned-farmer would have reason to get Holonet access with his family, and he could have learned about Commando Droids that way.
Yeah, but would they also get information which might be under military confidentiality, i.e. which might be considered either too classified or too troubling to be made public knowledge?
While specific details on Commando Droids might be classified, that is speculation, and simply what Commando Droids look like and are called is probably not going to be classified. This is a galaxy-spanning war, where keeping such basic info secret would be very difficult. The Separatists might broadcast it for propaganda purposes, and the Republic might for propaganda purposes, or to warn their citizens of what the enemy's most dangerous troops look like.
