Remember: the Jedi ONLY use the force for knowledge and defense. During the Clone Wars they would help with strategy, but I don't think they would lead assaults.

This is why I feel a distinction must be made between Jedi Masters (like Yoda) - "knowledge and defense" - and Jedi Knights (Obi-Wan), who actually do fight, but don't use the Force itself to harm others (as Sith do).

Basically, Jedi Masters don't fight at all, and don't have lightsabers, while Jedi Knights use lightsabers for fighting, but still don't use the Force itself for attack purposes.
