FMA: something missing

Should indirect fire be in the "core" rules?  Not sure about a
mechanic yet as I haven't played the rules (I have _one_ FT
opponent and he's out of town).

Now, not that I am complaining, but the x2 modifier on armour
needs to be written up in the core rules OR the reference to
it dropped.  There's nothing I hate worse than dangling
references in a set of rules.
