Two tracked artilleries but beyond that…the AS90 has better manoeuvrability, huge HE, great PF, overall smaller, an actual turret rotation. Meanwhile, the AuF is probably the sluggiest artillery of the tier, aweful ballistic (and oh boy that’s even worse with the PF round), is a gigangtic monster with a turret that could honestly be removed given how slow it is…
I’ll add that the PF round is the exact same one, except it magically goes from 810m/s on the AS90 to 580m/s on the AuF1.
So PLEASE, help me understand. If the AuF1 is worse okay no problem but it has nothing to do at the same BR as the AS90.
