We are the Republic's defense, while they are the offense. We stay at the defensive positions, and fight only if the Sith move onto Republic territory. We fortify the forts and bases.
Send a few Jedi to certain worlds that are under Republic control and Are vital to the Republic. Like REALLY vital. Then do what Malak said and just sit there and defend it rather than go on the defensive. Also, maybe have a few Jedi "Special Units" that go into the front lines and actually fight with Republic Soldiers.
This is not my idea, it is Balian Ibelin's, but the Delgations forum said that the poll will be up soon, so I'm posting it for him so it can recieve a vote.
Send Jedi, or small groups of Jedi, on missions to help restore the Jedi to their glory as well as other things. (the sabotage, gain support, etc.)
