Does anyone know how to kill Shemsher on Medium difficulty level? I saw this:

But this strategy doesn't work for me at all -- these bombers die much faster than I could shoot his turrets off. 'Evasion maneuver' orders doesn't seem to help. So far my best achievement was to shoot 3 (or 4?) turrets before he kills all bombers and switches on me. :-\

And yet in that video he had plenty of time -- maybe because on Hard level these bombers get better pilots?

Just for history -- I think he sent first bomber home (or got very lucky that bomber survived a hit and headed home on his own). If you carefully watch messages, you'll notice that right after he kills final turret bomber #1 enters hangar.

Reduce the DOSBOX's cycles, and try again.
