[DRG]

winSPWW2 and winSPMBT are a development of SP2. WAW was a development of SP3. They are all "a version of SP" but that's where the similarities end.

There was nothing in the GG explaining how CB worked because it took 20+ years for it to be an issue that needed explaining.

But to add to what Andy wrote...... the higher experience and morale of your CB batteries the more effective they are so in a long campaign your best batteries with the longest ranged guns would be the first choice to set aside for CB
