Welcome to Librarium Online!
I've got a list together after a long absance form my Tau. I've tryed a list like this already and got good results. but after some changed I'm short 150pts. I don't know what to add. Some Ideas are a Skyray, some fire warriors and kroot, or maybe add some drones to diffrent units, or another hammerhead.

-Shas'vre, Plasma Rifle, Fusion Blaster, Targetting Array, Multi Tracker.

Army's used: Space Wolves, Tomb Kings, High Elves, Tyranids, Tau and Eldar.
this is a pretty good list but there are some things here that are not very efficient. the fusion blaster and target lock on the stealth squad isn't that great since the fusion blaster wont be hitting half the time and getting close to use it is a real problem. also, how many are in the squad? photon grenades and rail rifles are not worth it and thier point are better spent elsewhere.
as far as your heavies go, the broassides are pretty solid. just make sure there prottected from assaulters. your hammerhead on the other hand need some upgrades! use burst cannons instead of drones for the extra shots and it almost required to have a multi-tracker and dostruption pods on your tank. they make it so much more effective.
Never give up. Never give up. HIT, HIT, HIT, HIT!
