@Uncrustable:
Get your submarines out of CRD range (you want the max capture possible.)
Im sorry what does CRD mean ?
“Convoy Raid Disruption” or “Convoy Raid Damage”. Basically, the round before Germany hits England, you want to move your subs out of the Convoy sea zones so Britain will collect their full income on their turn. Then when Germany attacks England, assuming they take London, they will plunder the British treasury and collect the max number of IPCs.
