Depending on the sector, access to the helm may be restricted outside of areas where the environment make its use mandatory. The [[Order of the Sacred Rose]] in the [[Kaurava]] system awarded it only to the most courageous [[Adepta Sororitas]], while the [[Order (Adepta Sororitas)|Orders]] of the [[Calixis Sector]] did not usually issue a helmet to a Sister until she had proven herself.{{Fn|1}}{{Fn|4}}

Some variants sport a [[wikipedia:Fleur-de-lis|fleur-de-lys]] mounted upon the front, an honour reserved for sisters having performed with exceptional courage and honour. Such insignas are common amongst the elite [[Celestian]] squads and the veteran [[Sister Superior|Sisters Superior]] leading their sistren into battle.{{Fn|1}}
