The statistics are fairly arbitrary. I do know a little bit about tanks however. My primary goal with respect to the main weapon each tank carries, is to score a penetration/kill within 1-3 shots at close range on the frontal armor of an equivalent tank, while requiring many more long range shots to score a kill. 5d10 dice are used to reflect the immense variability in damage - it is not uncommon for a sabot, especially at long range, to simply bounce off another tanks' armor, doing no damage. Likewise, it is entirely possible for a lucky hit to the turret ring to penetrate straight into the crew compartment. [Although the damage rules for Eclipse Phase really do not mesh well with tank design.]

The additional rules for ranged combat between tanks is meant specifically to represent the penetration problems tank weapons have over the extreme ranges they fire at.

I would also like to note, that for an average height person, the horizon is about 6-10km's away, and any tank firing over that distance will probably have LOS issues. Further, the extreme range itself probably isn't possible with modern day tanks unless they actually situate themselves on a large hill or mountain. Naturally the actual ranges of modern weapons are classified, so it's just guesswork on my part, but I've heard stories of Leopards/Abrams hitting targets 5+ kilometers away.

Also, I meant to include secondary weapons for the pre-Fall/post-Fall tanks, but got lazy. Normally, I wouldn't include half-done things like that, but I wanted them around for comparison to today's modern MBT's.
