No fluff on this one, because I'm seeing it as super generic, and kind of a counterpart to the STG-3P Stinger; it even uses the same main gun and engine.
First, I dropped the mass by a ton to 24 tons, to allow that GM 120 fusion plant to drive the tank at 5/8 movement. Next, the AC/5 and machine guns were dropped: we've got 10 single heat sinks in the engine now, and a light PPC has the same range and damage curve as a standard AC/5. We lose specialty ammo, yes, but we gain so much in return. Machine guns were also dropped in favor of twin SPLs, which removes the potential shrapnel bomb the MG ammo in the hull represented.
Next up, that free mass got ploughed into more armor, increasing it to the 8 tons maximum that MML will allow me to mount. Front and turret locations got increased to 30 points each, left and right sides to 22, and rear to 20 points. I'm considering dropping the sides to 21 each and increasing the rear to 22, so that it can take an AC/20 hit anywhere and still have some armor left, but I figure the merits of that are open to discussion.
Lastly, I had a half-ton left over. I could've added a standard small laser, since I had the heat dissipation, but decided that a single RL10 launcher on the turret might be a better use, since it gives a standoff panic button weapon, but a vehicular grenade launcher would also be a valid, and perhaps better, choice - thoughts?
Cost is surprisingly cheap. Admittedly, it costs about as much as two regular Scorpions, but it's also faster, twice as hard to kill, and has a minimal ammunition budget to worry about.
