Where a unit is in action, say HMS Liverpool in the Med, then there is a world of difference between my aunt serving in Cairo and in action at sea. If the captain be deemed worthy of an honour so too should all the followers. Drawing lots might satisfy the top needy but cheese off the indians. I know, been there at both ends. The last had this young woman 'attack' me spitting feathers.
Rosettes, bars, MiD oak leaf or whatever would signify special service.
