A Hidden Member

[Jack Shipsteel]

But an invisible officer is just like a veteran, no?

A veteran can only recruit, yes. However, they seem lesser than the officer to the rank and file members. Don't get me wrong, veterans are just as important as officers, however, they can only recruit in the members eyes, so there's no reason to behave.

Part of a veterans job is to report any mis-doings to an officer. The officer can take further action.

Invisible can mean many things. But the visible who can act invisible are truly dangerous. There's no need for an invisible officer if you have a rank such as veteran.
