Miniature aggression drones are small, bee-like drones intended to harry individuals threatening the augment who released them. They serve as interpersonal chaff, running interference while freeing their host for an escape or other activity. Usually, MADs are released from the torso.
It is very difficult to properly weaponize MADs, but it is possible - usually through associating them with another device power the host has.
Each rank bought of MADs enables another 'group' of drones to be released. As these are large numbers of physical constructs, the drones take 24 hours to reconstruct themselves.
