**'''NOT RECOMMENDED''' for normal clear, only use this comp for this particular quest due to the nature of 6-4 east route preboss having a lot of dangerous enemies that can potentially wreck your ships.
+
***Node M is full of So-Class submarine, while node K and J each <font color="red">'''having CV Wo Kai Flagship, accompanied by either BB Ta-Class flagship or BB Ru-Class Kai Flagship'''</font>. With all these highly dangerous enemies awaiting preboss, a proper fleet with strong ships and equipment are required if you wish to bypass all these nodes safely.
+
**LBAS can be used preboss to help bypass easier, but may suffer the boss fight if you lack of good anti-installation equipment.
+
**Keep in mind that [[Artillery Imp]] at the boss node have fairly high AA that can easily wipe your bombers on your CVs. Do consider the bombers that have AA resistance so that your CV can at least do the shelling and take out some of the escort enemies.
+
**CAV can be replaced with LHA to '''skip node I''', which is an air raid node, but LHA may have some issue surviving the preboss.
