+    # sort of hit damages devices.  The probability that a given
+    # device is damaged depends on the device.  Well protected
+    # devices (such as the computer, which is in the core of the
+    # ship and has considerable redundancy) almost never get
+    # damaged, whereas devices which are exposed (such as the
+    # warp engines) or which are particularly delicate (such as
+    # the transporter) have a much higher probability of being
+    # damaged."

+    # This is one place where OPTION_PLAIN does not restore the
+    # original behavior, which was equiprobable damage across

+    # We don't have a cloaking device.  The shuttle got the allocation
+    # for the cloaking device, then we shaved a half-percent off
