A good way to answer that question is to switch sides for a sec...
You are a UWM councilman, discussing how to deal with the worker rebellion on Hephaestus. Known assets include massive industrial capability and advanced defense systems, notably including laser batteries which will shoot down most incoming projectiles. They may also have seized some dangerous weapons from an HMRC craft which was scheduled to dock there around the time of the rebellion, but this theory is unsubstantiated. They have a year to prepare, as well, and they will likely use this time to make weapons, more defenses, and war machines.
What weapons and such would you advise bringing to quell this rebellion, with minimal loss of life or property?
A shit ton of competent amp users backed up by sods, etc, have a few snipers with LESHO rifles in the back, and 2 or 3 fission instigators should things go to shit.
