The Combined Arms Penalty

Marvellous. That's a pretty clear explanation John. So basically both units are 'firing' at each other and this shows the casualties they are likely to inflict on each other.

A lot going on under the 'bonnet' there...... (or 'hood' in US)

Yes, it shows the relative attack values before modifications. But in assaults the casualty calculations are different depending on whether you are the attacker or the defender.

The casualty range relevant for a given attack is determined using the High and Low 'Combat Losses' values in the parameter data. For assaults the High and Low values for the attacker are typically twice those of the defender. So given the same attack values the attacker initiating the assault will suffer twice the casualties, on average, than the defender would.
