3.4.2 Attack the incoming UFOs
[FAQ] Usually you can detect the UFOs as they come in for the
attack. Shoot them down first. If you got Hyperwave Decoders,
watch for UFOs with "retaliation" missions. Those are coming
after your bases. The small UFOs that come first are scouts. If
they see your base, then comes the battleships.

[KSC] [Not verified] If you managed to intercept the attacking

it outrun you.

[KSC] If you attack the incoming battleship with interceptors
you'll lose them. Do NOT attack battleships with interceptors.

[Doug] If you think you can hold your base, you can let the UFO
through and just fight the ground action. Of course, you risk
getting your base wrecked, but you also get chance to capture
aliens and alien equipment.
