The jackson needs enough HP to survive 2 heavy-TD shots with at least 20HP (to prevent abandon RNG), so that the jackson doesn't become useless.
(Note that jackson still has a massive 24 target size, which makes it a shell-magnet)
The jackson also requires 60 range still, because there's no other way USF can survive vs 55-range OKW Panther.
Finally, USF requires a unit that has decent penetration up close, because there's nothing else that USF can throw at a King Tiger camping at the "wrong" type of maps.
The jackson should have good enough cost-efficiency so that USF can fight it out vs heavy armour in the late-game.
Finally, the jackson should have low enough accuracy and low enough cost-efficiency to prevent Jackson from hardcountering everything on wheels.
So, that's what the design of v1.1 Jackson looks like.
Well..than you must nerf the rifles and/ or the pick ups they can get.
terminator infantery and tanks? sounds a little bit to good
