Oh, I do love this genre...@LetMeDoStuff
, I do have a concept for a "network security specialist" type character I created for another RP months ago that never actually took off. Essentially they work behind the scenes for the most part, from either an NSF home office or perhaps remote safe house (depending on where the group is positioned) and are tasked with getting the team in & out of secured areas. Dealing with most security measures as needed.
They do have combat/self defense training, etc, however, I was thinking of having them confined to a wheelchair due to an accident that caused irreparable lower spinal damage, so there won't be much field work for them. They sort of work behind the scenes.
Anyway, let me know if this concept works for you.
