Maybe in the mod,because in live you need to be extremely careful with it, as a single PZ4 sneaking up to it will usually beat it in a duel, USF needs a unit to be their heavy duty AT unit and the Jackson is perfect to fill in that role and give USF a better shot at closing games.
This is thread about the MOD and the changes that come with part of which is increasing the M36 accuracy that will allow it (by vet 2) to hit a 222 at range 55 with 94% chance.
The unit does not need and accuracy buff instead it needs an accuracy nerf. It will still be able to hit the heavy tanks but it will simply not be able to snipe medium tank from max with 100% chances (vet 2)
There has been a trend of increasing the accuracy of TDs (Su-85,Su-76,M10,M36) which creates allot of problems and offers nothing in return.
