Continuity: When the ARC troopers are on Muunilinst, there is a red trooper, 2 blue troopers and several plain white ones. But on Hypori, there is still the red one, but the rest are blue.

Continuity: Season 1 Episode 3: Chapter III. The red-marked leader of the ARC Troopers sure goes through a rapid succession of field promotions and degradations. In Chapter III, he is addressed by Obi-Wan as a Sergeant; when Obi-Wan arrives at the Banking Clan's HQ in Chapter IX, he calls him Commander; and when Anakin returns from his duel with Asajj Ventress in Chapter XX, he is suddenly a Captain.

Continuity: When Anakin prepares for take-off, C3PO and R2 can be seen standing right by his fighter. But as he takes off, they can suddenly be seen standing by Padme – several floors above ground.

Continuity: During the meeting in the Chancellor's office, Yoda and Obi-Wan are at opposite ends of the desk. In the next few shots they are sitting much closer together.

Continuity: In the scene when Obi-Wan is telling Anakin that he is the Commander of the space fleet, in the overhead shot only Obi-Wan is walking near Anakin's fighter, yet in the next shot Clone Troopers are marching right past the fighter.

Continuity: When the LAAT gunship is shot down by the rocket, it crashes into the street with the upper side (with the cockpit canopies) skidding forward. But it comes to rest with its nose forward, and in these two shots it has made no visible spinning motions.

Continuity: As the ARC troopers' gunship breaks off from the rest of the ships and as it's flying through the city, its markings are blue. But as the ship is hit and crashing, its markings are the red. (It is definitely the same ship, as we see the ARC troopers emerge from it after the crash.).

Other: When the ARC Trooper gunship is hit and goes down, there is a brief shot of the Troopers standing in the compartment. None of them rock or fall to the side as they should, especially when not seated.

Continuity: Season 1 Episode 3: Chapter III. After the ARC Troopers have destroyed the Droid tank, the Captain waves the team on. In that shot, the red coloration of his helmet's chin is missing (it is white instead).

Continuity: We see one Clone Trooper get hit by Sniper fire and fall in front of the ship, yet in the shot following his body is off to the side above the crashed ship, not in front.

Continuity: When the Sniper Droid zeroes in on an ARC Troopers head, we see them in a ring around the gunship, with 2 ARC Troopers on top of the wreckage, but in the shot after that we see them in a completely different position, with all the ARCs in front of the ship.

Continuity: When the giant beam gets fired by that lobster cannon, the positions of the ships on the surface change instantly between shots.

Other: In the Banking Clan's HQ, San Hill assesses the situation: "Those guns are destroying our forward positions. The Republic is breaking through!"; then the ground shakes when the giant cannon outside is blasted, and Hill flinches in surprise. But if you look closely, he flinches just before the explosion and the resulting tremor come in.

Deliberate "mistake": At the beginning of the chapter, as the scene switches to the surface fighting on Muunilinst, we see a score of droids blasted before the Republican Army's heavy artillery is brought in. But there are no remains on the droids to be seen after the smoke has cleared, whereas there should be something left.

Continuity: When Count Dooku and the disguised Asajj Ventress watch the fighters in the Rattatak arena, the lodge they sit in at first seems almost level with the arena floor. Later, when Dooku floats to the arena floor after Asajj has finished all enemies, the lodge is high above the ground.

Other: The crest of the clone trooper's helmet, when he points out that the cannons are being destroyed, does not reach down to the eyeslit, whereas it does with the others'.

Continuity: When Durge fires his in-built flamethrower at Obi-Wan, the Jedi Force-crushes the weapon. but in the scene where Obi-Wan's hand is closing into a fist, the flame stream stops just before that; and when the scene switches to Durge's arm, the flamethrower is still firing just before its muzzle is crumpled up.

Continuity: During the first duel with Durge and Obi-Wan, Durge's bike is totalled and Obi-Wan's gets hacked to pieces as Durge swings it at Obi. However, as soon as the fight is over, Obi-Wan picks up his bike, completely undamaged, and goes off on his merry way. None of the other trooper's bikes are ever seen anywhere near them.

Continuity: The coloration of ARC Trooper Captain Fordo's helmet changes several times during this episode.

Other: After Obi-Wan has finished Durge, the ARC Trooper leader steps up to Obi-Wan. Although he approaches from and stands somewhat behind Obi-Wan, he turns his head to the side as if they were standing side by side.
