That's not really a problem for me. Extensive landing operations are not my thing. The shore batteries are certainly dangerous enough for submarines. Would be worth improving, however, that these guns basically have a field of fire of 360 °? Because I wanted to know that, I had two batteries installed on a slope rising behind them. Waypoint at sea. When I came in the 180 ° behind bay, I could not see a gun, but got for "upgiving/unlearning" purposes
neat firing from these two batteries. This explains the old saying: When fire falls from the sky ...
Where people can find this "...confounded gun emplacement..." I don't know too. Maybe an archaeologist on Henderson Field can help?
