20 metres area-fire buffer zone

[RockinHarry]

The game assumes infantry to be evenly spread within a tile, thus this 20m pseudo safety distance. In fact there is not any.

standard distance between single infantry men (in german army) was normally 4-5 meters when in employed formation and so one can see that a squad of 10 men would distribute more over 40-50m, instead of a standard 20m CM tile. Internally this is taken into consideration and a HE shell that appears to land 20m far off an infantry squads 3D icon and causing a casualty, might in fact be a direct hit on a soldier that is abstractly assumed to be farther away (from the graphical representation of the squad).
