Deleting units from factions

[Noir]

Try taking out the buildings that make the unit and leave the column blank. That should do it.

*edit* Just realised that this isn't perhaps very helpful as it will take the unit out from all factions (nobody will be able to build it).

For ownership columns IIRC leaving them empty simply means that everyone can make the unit. This is probably why it does not work. You could try also "giving" the unit to a faction that won't be present (Russia, a muslim faction).
