[snip] Still disappointed by the performance of the CD unit. The one source I consulted listed the forces at SF on 7 December 1941 as 6th CD command, three CD BTN (not one), plus two NG RGT's.
You will find that all the coastal defense guns in the San Francisco Bay Area are included in the "Harbor Defense" CD unit. During the design of AE, each nationality was assigned a fixed # of LCU OOB slots -- so one of the slot-saving techniques was to roll all of the American CD units in each port/base into a single unit.
In theory, a single unit might be easier to disrupt/suppress than 3 separate regiments. When we play-tested, it didn't seem to make a difference. Sometimes the CD guns rip up BBs, sometimes they complete disrupt the landing LCUs, and sometimes they just don't seem to fire very much.
