Command & Conquer 3 Kane's Wrath?

I believe that Cabal Confesors happen to be infantry units. Personally, the best defence against infantry depends on your faction. If you are GDI, build more sonic emmiters than machine gun turrets. If you are nod, you should use Reckoners because they have high defence and hp, and load them with anti infantry infantry(ex: militia, and or advance infantry). If you are Scrin, then you are pretty much screwed because scrin has the WORST anti infantry defence ever. Believe me: I know. My best record for gameplay in C&C 3 was 7 brutal enemies all allied against me. If you would prefer to use units for base defence, then that would entirely depend on number of enemies. In any case, you should build 1 reaper tripod for every 5 cabal confessors because of the confessors special ability(supports combat effectiveness of all allied infantry).
