is there any way to tell how many shore battery emplacements a field has without actually going to the field in question? Thanks in advance.
No, you have to do a recon, some have no SB's, some have one and some have two.  I don't recall seeing more then two on any location.  They seem to take 3000lbs of Ords to take down, are down for 15 min.  Resupply does not help.
