That's about what I thought of regarding accuracy.
For guided submunitions I used a basic downgraded seeker accuracy (accuracy of one submunition), then growing logarithmically (10*log10(n)) with the number.

The problem being that, if you go any forward in this reasoning (more rounds => more P(hit)) you end up linking the accuracy of MGs and autocannons (and sniper rifles f.e.) to their intrinsic RPM rate of fire.

Tuccy, have you tested your HEK=2 weapons to work?
Actually smart rounds like the Motiv or Bonus or Skeet are bound to kill nearly no infantryman, even in the open, since they are specifically AT with an IR seeker. That would be tough luck to catch one on the head or stay nearby when it self-destructs!
