10-12mm scale modifications
The nuance of using smaller scale miniatures requires the following changes to HCM (the intention is NOT to change from the existing 2.5 inch flat to flat hexes)
Items in a hex: The visual appearance of a single 12mm vehicle in a hex hints that more than 1 tank is likely to exist in a hex, but again, not likely more than 2. This is also true of all other items such as infantry squads, and now, entire batteries of anti-tank guns might be seen on the table as opposed to the normal 1/72 scale of seeing only 2-3 ATG for the entire game. Large guns from 88mm and up occupy more real estate so no more than 1 per hex is likely the norm, but in this case WITH their limber/transports in the same hex.
Items in a hex: If in 1/72 infantry squads are based on 1.5 inch round stands, with for safety reasons no more than 2 per hex, then either the same will be done for smaller scale figures or else the figures might be mounted to 1 inch round; hence, up to 4 squads might exist in a hex without violating any principles of space and safe operating distances. Ergo up to 4 with a vehicle etc. is possible.
Ranges: Hex Range Bands will be adjusted such that the appearance is kept within standards; 2 hex for all cannon fire and 1 hex for all small arms thus 1,2,3,4,5,6 hexes; for cannons Automatic 2 hexes, Color (blue) 3-4 hexes, Code (red) 5-6 hexes and CnC (Star) 7-8 hexes, with an additional CnC band for special range items (HMGs etc). 3 hex bands might be possible but until testing is completed 2 seems to be correct.
Indirect Fire Ranges. Regardless of the scale, maximum indirect fire would still be the entire visible battlefield (4x3 or 8x5 table size), but mortar ranges should be stipulated: 20 hexes, with heavy mortars being 36 hexes maximum. Note however that reports of mortars being accurate of effective at their farthest range are debatable.
The use of 12mm does not obsolete 1/72: in fact, 1/72 can still be used for focused-actions, e.g. if 12mm results in a battlefield of several villages, 1/72 might be used for detailed gaming for just one village.
