There's nothing wrong with the jackson. It's perfectly fine. The problem is that it's really the only thing that can hurt armor. USF needs more anti-armor options not just to buff their only good option til it's OP.
I kinda agree with this.
It's just, the USF have no damage-soaking unit thus they need to engage tank battles extremely cautious.
That's the thing for me that I don't like about the USF. A P4 can easily escape situations that shermans or Jacksons can't.
