Has anyone managed to beat insane 3 duo?

My bud and I play a couple rounds of survival every day, and every day we feel like the bot's get the perfect counter to whatever we've built up. One time it's going crawlers only to run into 3 waves of high tier mustangs with HE and range, other times it's 2 rounds of storms with HE,Elec,INC, and launcher overload all backed by tanks and air.

I've beaten Insane 3 & 4 with a random guy. It was intense but in the end doable.
You wanna know something more or is that the only thing you wanted?
