On Oceania most of the feilds are 19 miles apart so I had to get really creative with the shore batteries so you could not target the closest runway spawn to the sea at the next field across the slot or drop rounds into your own town or field. The reason for the mountain side SB. Spent days micro adjusting the positioning of SB's. The clover leaf islands on Oceania I setup the SB to command the center of the slot they faced. I've never asked Hitech what his limit is for shore batteries at a field, I've had complaints that amount to wanting me to place an SB one every mile or closer together surround every field. When I got deeper into the reasoning, it's the same reasoning from tank drivers. A player is alone at a field and notices a BB shelling it and he is way past the time period the BB was in the gun arc. The single player does not want to up bombers, he wants to sit in a big gun. Tank drivers in the game want spawns on elevations over fields so they can single handed de-ack, kill the VH, and drop the town.
