Trying to stay within SR5 as much as possible, I see a TacNet doing several things. First, it functions as a micro-host, hiding and protecting all it its members at its device rating while still providing slaved devices online matrix access.. Second it allows secure communications. Third, it could provide a shared initiative pool based upon its rating. Members of the net could draw from the pool to automatically aim for example. The TacNet could provide team limit and BD pools based upon its rating as well. As a complex action, the TacNet operator could make a leadership or some other test TBD to refresh the pool (it doesn't automatically refresh). These pools, could be attacked and depleted (2 marks) or stolen (3 marks) by opposing hackers. Also, a compromised TacNet would give an opposing hacker complete access to the squad's logistics and allow him to directly attack/manipulate slaved devices.
Finally, a TacNet would require a minimum number of inputs per device rating to operate (additional inputs would exceed the TacNet's ability to adequately process, thus providing no additional bonus. A TacNet who's inputs begin to drop off degrade to the next lower rating that it has the necessary inputs to function at.
I realize this needs some fleshing out, but I think it could be a good starting framework.

Like it.
It should also automatically prioritize targets. A character with tactics can improve things in someway based on the incoming data. IE do a better job prioritizing targets. Directing flanking manuevers etc.
