Modern self-propelled howitzers, for example the Panzerhaubitze 2000, are capable of using a computer generated firing solution that allows multiple rounds fired from the same gun to hit the target near simultaneously, this improves efficiency of the barrage as the target has no time to react and take cover.

It is 2035, so it would be nice if the SPGs were able to do this, you can already do a two-round simultaneous impact on some ranges and with manual timing, but an automatic system incorporated to the artilley computer would be awesome.
