>When selecting units for an Auxilia Veletaris Tercio, one Solar Auxilia Hermes Veletaris Squadron unit can be included in place of one Solar Auxilia Veletaris Storm Section unit.
Am I reading this right that each Veletaris Tercio can only include one Hermes Squadron? Can the Squadron replace the one mandatory Storm Section in a Tercio or does it have to be one of the other two?
