Thug/SC warfare question

[Deadnature]

There are numerous guides/tips floating around these forums about creating good thugs and SCs. As a semi-noob, I find that doing well until late-midgame/late game is no longer a problem for me.

However, when it comes to fighting the late game wars I seem lost about how to pursue a decent strategy involving thugs/SC, both in defending against them and using them offensively. A particular problem for me are the flyers, is there a decent way to intercept them other than guessing their next destination?

thanks in advance guys,
