I wish you hadn't fallen for the trolling, Wes. Fine. Following your lead. They weren't yours to describe in the first place because they were my submission, Wes.
(though I'd point out the present 'touched-up' version of the article actually seems inferior to the original)
Nodal Support Drones aren't Nodal Support Bits. They're already larger than the 'finger-sized' NSB, meant to have longer range/be more capable/have a size that's not ridiculously small for what they do. Think of it as a nekovalkyrja service pistol as centerline of a karate chop-shaped adult hand, with the magazine handle being turned into an extrusion of the centerline underneath the drone (which is also the drone's attachment point to the upper leg hangers). The volume on each side of the centerline weapon includes components for the drone's sensors, communication and mobility.
Thing is, much like most bullets and mini-missiles, this never really needed an indept description; technicians and roleplayers seldom actually need to know how exactly these things are like beyond the information already released.
