Ok, This is only small, so it won't take up much of anyone's time, Is the combo file the unit uses defined by the unit's name? For example, if my unit were to be cis_hero_darthsidious, would it use the combo called cis_hero_darthsidious?

No. The combo a unit uses is defined by whichever weapon they are using. Look inside (for example) Darth Sidious's lightsaber's odf file and you'll see.

K, thanks!
