personal weapons for more heads?

[Theunsolved-puzzle]

The MD has a weapon to defend medbay, which is always under assault. but also to keep super powered genetecists in-line with his mutadone rounds.

if the weapons/tools are to counter certain challenges the department heads face, maybe give related ones then
give the RD something like a SUPER neutralizing tool of some kind, that removes chems from the ground, removes aresol, deactivates arts, etc. (basically a cleaning grenade on steroids)
I don't play much engineering so I cant talk much for the CE
for the HOP, there isn't really much of any weapon that's justifiable for them to have, most I can think of is a ID disabler for when someone gives themselves AA, though that does sound more like a HOS thing even if it deals with ID's and acess.
