Secret Weapons " Secret Weapons " is the tenth episode of the . It first aired on December 1 , 2012 . Official description . " " R2 - D2 is part of a team of Republic droid s chosen for an important mission led by the diminutive Colonel Gascon to obtain an encryption module from a Separatist dreadnought . The droids must overcome numerous challenging obstacles to succeed in this crucial assignment . " " Plot summary . The Jedi High Council has devised a plan to capture a Separatist decoding module from within the vault of an enemy battleship . Since the mission involves a special level of infiltration capability , the Council has decided to employ a team of handpicked droids for the undertaking . Thus , several Republican droids are assembled in the Jedi Temple war room : the astromech droid s R2 - D2 , QT - KT , M5 - BZ and U9 - C4 , as well as WAC - 47 , an overenthusiastic and bumbling pit droid who promptly arrives late for the mission briefing by Master Windu because of a hearing mistake and thus does nothing to garner much confidence from the others . The mission is to be led by the diminutive Colonel Meebur Gascon , a highly esteemed strategist for the Grand Army of the Republic . Gascon , whose strict and no - nonsense attitude immediately is off to a wrong start with WAC ' s flippancy , wastes no time going through the finer details of the plan and takes the droid to see the technician Dr . Gubacher , who outfits most of the droids with special gadgets for the mission . WAC , however , is exempted because he is to take the role of the pilot for the team , while M5 - BZ has his memory core is removed so that Gascon can use him as a disguise and rolling command platform . As the mission begins , WAC over - confidently decides to take matters in his own hands by setting their transport shuttle on a collision course with their targeted ship in order to attract its attention . The result of this maneuver gathers a bit more attention than necessary , as the shuttle is taken in by a tractor beam and the dreadnought ' s droid crew proceeds to cart off the astromechs off for interrogation . The droids , however , manage to overpower their guards and sneak away to initiate the next step of their mission by having C4 cause a temporary power outage to circumvent the security settings at the decoding module vault , and WAC successfully manages to dupe to the droid guards stationed outside the vault . But when Gascon attempts to open the vault door , he accidentally inserts M5 ' s tools into a power outlet , causing the astromech to suffer an enormous electric shock . Gascon then unexpectedly appears unsure about what to do next , and under WAC ' s questioning , he reluctantly reveals that while he does have a reputation for being a tactical analyst , he has no real field experience whatsoever and that he sees this mission as an opportunity to promote himself . Upon WAC ' s challenge to treat his team with more respect , Gascon and the droids finally find a common ground and make a truce to see the mission succeed . The droids manage to disable the security measures within the vault itself and penetrate to the module storage chamber . However , their undertakings have caught the attention of the ship ' s droid commander , Aut - O , who arrives on the scene with an escort of battle droids to investigate . But R2 , who conveniently stands near a control pad for the chamber ' s artificial gravity , promptly turns it off , causing all the droids to float helplessly around . This gives the droid team the opportunity to finish off the battle droids ; Aut - O still remains functional and attempts his best to thwart them , but by cooperating , Gascon , WAC and R2 manage to put him out of commission as well . Aut - O still manages to sound the general alert before he deactivates , forcing the team to evacuate immediately . At first eager to leave to prevent their capture , Gascon consents to his team ' s wish to take the damaged M5 with them , and amidst the hubbub the alarm has caused , Gascon and his droid team manage to slip away with the decoding module in their possession and a newfound appreciation for each other .
