Your strikes should be just about finished now, no rush if they aren't, take your time. I would recommend you try this again and experiment. First you may want to load up your save game in editor mode and check out the Red side to see what the actual damage is, compared to what your BDA is telling you.

Another idea instead of the multiple strike missions is to make a patrol mission, name it Holding or Marshaling. Turn 1/3 rule OFF, set flight size to pairs, and assign all your aircraft. Then you can micromanage the attack and bring your aircraft in at your leisure. You will need to hit "U" to unassign them from your holding mission before you conduct your attacks though or it might confuse them, their only pilots after all. Careful that the Reds don't scramble on you once they see you coming though.

When you have large strikes, with dozens of aircraft, this marshalling technique is a good way of setting things up, getting everyone airborne and dump them into a strike mission all at once to overwhelm heavy defenses.

See you in Tutorial 4, where the enemy might try and fight back.
