Yet another own goal Raggy:

"in full view of the population of the city they were trying to subdue."

Would that be the population that was cheering the British troops on Raggy? The population that DeValera purposely put at risk, while at the same time claiming to represent - I'd have told him to f**k-off and represent somebody else, in 1916 preferably German?

Ranging for NGFS? Two possibly three shots to direct the guns onto target then once the order "Fire for effect" is given there can be anything up to 60 shells on their way to the target before the next shell lands. Even HMS Belfast tied up in the Pool of London when in commission could manage 120 6" shells - I believe that she was once used to stop an attack by a Panzer Division that was threatening one of the landings in Italy.
