Damaging a Ju-88

In all honesty, I find rule 6 for damaging a Ju-88 (Table M-2) difficult to remember. One might achieve the same flavor (Ju-88's are hard to destroy) like this:

Table M-2 Modifiers for Ju-88's (Additive)
-2 — start with -2 as Ju-88's are difficult to destroy.
+1 for Ace Gunners — a special rule for Ju-88's.
+1 for Quad Guns — if all four are operational. (The usual treatment of the quad tail turret.)

Remember that these modifiers are additive. For example, an ace gunner in the mid-upper turret and a non-ace gunner in the tail turret would both be at -1 on Table M-2.
