I need to be able to check if a sector belongs to a certain faction, so it can be used as the condition for a trigger. For instance if a certain sector belongs to BLUFOR/WEST, then a trigger will be fired.   I ask because although I am aware of the 'expression' variable in the module, it seems to trigger at mission start and when a sector starts to be captured.   EDIT: Also does anyone know what the sector (dummy) module does? The only behavior I have observed is that it becomes capturable as a sector if you sync it to another sector (from which it appears to inherit parameters).
