France '40 - 8,8 Hard Attack Value

[Green]

Understood, more or less.  

As usual, bringing this knowledge to real life is hard.
I tried it in the Arras scenario, moved the B/7th RTR to 8,16 besides the 88 battery at 8,17.
The Fire value I get in the report is 249.
But I don't get to that using the formula from the manual. It is afaik 1/squareroot of 2,43 what is about 0.64.
The Fire value of the 88 would then be 16(guns) x 39(hard attack value) = 624 x 0,64 = 400
400 is pretty far away from the shown 249...

The calculation is;

Combat Value = H x Number of Guns x 10 / D x (1/ Square Root ( H / D))

Where H = Hard Attack Value and D = Defense Value. The number of guns is multiplied by 10 as 1 gun = 10 men.

So plugging in the values gives;

CV = 39 x 16 x 10 / 16 x ( 1/ Square Root (39 / 16 )) = 249.8

This is value displayed on the Combat Report (rounded down to 249).

There is a 20% reduction applied to this since the unit is Quality D but the CV is shown prior to this adjustment.
