Well hopefully with the new AHII terrain the Blitzkrieg/Kamakazi gv runs to bases and towns will be knocked down a few notches. With the tree layouts and all there is very few direct routes to the base/town. But laying land mines would definately be a good idea so as to strategically force enemies to come down coordioors to the wolves.
Not sure if PT boats ever had the capability of dropping mines but if they did that would be a good idea also. It would or could help limit the half a mile off shore flogging that goes on now to bases and towns. It'd also force medium to long range shots from the CV gunners. And at longer ranges the gunners would need a spotter for precise aiming. Plus since when wasn't most ports mined for security? I'll have to look this up and see if and how often ports were mined.
