Its been mentioned in a couple of places that in V3, charge ranges are measure from any point on the units front facing rather than just the units leader point.
This has a couple of nice implications. It stops units if the same speed being able to put themselves in charge range, but stay out of range themselves and it massively opens up charge ranges for large fronted hordes.
I’ve put together the grid below just out of interest to see how much different units ‘gain’ from the new rule. 25mm infantry hordes can now reach out 3.8" further than they could in V2, that’s a really nice buff for big units that have traditionally struggled to manoeuvre. It also means that dwarf hordes no longer have to worry about not being able to reach an enemy that’s stood right next to them!
