Tau Mega battle!

[Battle-Ranch]

So some friends and i are haveing a 20000 point apoc battle in a couple weeks. Imperium of Man Vs the Tau Empire. We have 1500 points of SOb's and about 4500 guards men and about 2000 Rightously Zealous Black templar and a bunch of other unconfirmed stuff vs 10000 points of Tau'ieness.
its half city fight, half "desert"
my troops are stationed with the SOB's at a church in the middle of the City with the job to Delay the Tau till the Guard can Shell the Herecy out of the tau

my idea is to lure the tau into the city and grab them by the belt and make them duke it out with my marines. what should i keep in mind when fighting the Tau?

as a relatively new tau player I can tell you
Hand to hand with a marine is exactly what i want to avoid at all cost so lure them in close and assault them
beware of fusion and plasms guns(tau plasma are only S6 but they dont over heat) and they rapid fire
take out anything with a markerlight and a seeker missle first and then they are pretty dead in the water.

about the seeker missile thing. The tau player is most likely going to keep the seeker missile firers way in the back since they have unlimited range, so the easiest way is to eliminate the markerlights, which is usually pathfinders and squad leaders.

luring in might be a bit hard as the tau have quite a bit of range. Also, be extra wary of fish of fury, because since it's in a city, the tactic can be used with buildings blocking either side, making assaulting almost impossible.

also, crisis suits! I just got the insertion force and I can tell you crisis suits are awesome. Customizeable to be prepared for anything and they're jet infantry. They can carry long range missile pods, piercing plasma and fusion, flamers, try to think up a counter measure for them.

Deep strikers are a tau's worst fear, espicially if it can cut off their escape, so definitly bring along assault marines. And make good use of your cover!

take some drop pods & deep striking termies. that will give you the protection you'll need from tactics like the fish of fury. for your deep striking units, take heavy flamers as well when given the option; templates murder the tau!

also, it's a good idea to hold back a few of your units to counter things like the aforementioned insertion force!
another trick is to pick on any stealth teams as they're key to the rest of the force's deployment...

take a blind barrage as one of your strategic assets. they're dead brutal! the only things they don't protect you from are flyers... hopefully your guard ally is bringing some AA support because the tau have some insanely nasty flyers like the tigershark... still, it's fun to lay the barrage 1st turn and then march a bunch of your assault force up behind it!
also, assests like the flank march can be game breaking when played well - just beware of getting hit by the sniper asset which can stop your flank march dead in it's tracks!

cheers!
