Yeah, they're skills. So for example Clearsight + Sensor for Perception tests.
Autosofts are programs accessed by the Pilot
program in drones. They serve as skills to augment
the drone’s performance. The attribute used with
each autosoft is included in the listing
If you were to group half a dozen Blackhawks (rules don't say you can group other drones but it'd make sense, especially for groups that throw out a Perception net), they'd count as 9 so they'd get +8 AR and +4 dice. Now page 203 mentions grunt groups can also be used in other tests, such as resisting Con. So a strict reading would say 'Blackhawks only, grunt attack only', but a GM could for easy usage let you group all your drones for Attacks, Clearsight, etc.
