TSK 9 tip for an easier win
I also looked through all 3 pages of topics, but nothing on this tip.
So, if you want an easier win at TSK 9 there is something you can do at the start of the game.
As you can see in the screenshot, at the start the towers don't have ammo.
So you can just walk behind them and destroy their storage building and other things.
Eventually they starve to death.
Then you only have to deal with half the purples forces and the other color that is building in the right down corner.
You can also build all the way up there and get the resources, they haven't been drained far if you go right at the start.

Note: I do remember the towers having ammo at the start of the original, but that was easily undone by charging 3 guys past it. a few might die but eventually they didn't have ammo and you could just walk past them
