Yup, that's it. But because of that, I needed a downside.
So, a gunner has to be guiding it by wire, not a computer, because ECM would render radio signals useless. You want a vehicle, not a Mech, because the Mechwarrior is too busy to be spared to control it, and most Mechs don't carry a gunner. Weather conditions affect how well you can see the target through the camera, and the launcher needs to be stationary to keep from tangling the wire. Nor can it fire into or out of woods hexes because the trees tangle the wire and snap it. Add the fact it can't be an enclosed weapon (not surrounded by armor), fed by a magazine, or engage an airborne target, and its a near match for a RL weapon.
Besides, according to the fluff, its developed by the Civil Government of my AU. The Clans are rich, successful - the CG population is cherry-picked for the best, the brightest, the most successful. Their educational and industrial base would be about equivalent to the Outworlds Alliance. Primitive tech is what they have to fight back and defend themselves with. For them, the Thunderbolt/TOW is cheap and simple enough to manufacture, able to shoot out locations besides the facing one on enemy units, and can't be jammed by the expensive ECM systems the Clans can (barely) manufacture.
So, big bonus being able to fire over hills and still get a change to make an aimed shot, but you're dependent on good sight conditions and dead meat if you get caught in the open, although you can always hope he's going to shoot at somebody else while you're a sitting duck. I think its fairly well balanced, it worked well in playtesting. What do you think?
Although, back on topic.
