Under current tabletop rules, PPCs (as ammo-independent energy weapons) may be used for strafing attacks. This is difficult to square with their operating principle, which fires a single discrete burst of protons/ions.
Speaking purely from an in-universe perspective, is PPC strafing possible? If so, how? What does it look like?
I'm assuming, by the way, that strafing with things like machine guns, chemical lasers, and even autocannons is technically possible, but catastrophically ammo-inefficient to the point that it is never done on the scale of multiple 30m hexes.
