by 'hex' i mean one of your 'nodes'
No
Hex its a square - in our game up to 4 node and 4 platoons.
oh so, it is still one unit per node then. That would be my one critisicm of this brilliant sim, that the great looking realistic maps are often far too empty of units. Knowing the size of Russia and how thin units were often spread to cover ground, then perhaps this is realistic but it does seem weird that a town the size of Taranovka has just the odd platoon roaming around. It just feels a bit 'empty'. Taranovka was surely held by at least a battalion ?
Now (with december 2011 patch), men count is same like in reality (if we know it). In Taranovka (march43) defence 9 coys (regiment) with support from Red Army, and approx 2 regiments from German side.
Even the siege of Cholm had 2000 men approximately, surrounded in a small town.
2000 men it's smallar than in Taranovka defence operation.
Taranovka it's not a town - it's a village.
You say computer power limits force sizes but cant you put in an options choice for unit sizes?
In option available radius of battles. By default in middle value (approx 12-17 platoons in battle).
