Irregular units never utilize Deception effects (to disrupt enemy movement or hinder bridge demolition).

The irregular units have DECEPTION in their alternate characteristics display.  If they do not disrupt enemy movt or hinder bridge demolition, what do they do?

I would suggest they have been placed in the scenario with a view to hindering bridge demo.  Perhaps the icon for partisans is incorrect [I] instead of [P].
