For his entire army, yes, I believe so. Hell, I have...let me see....5 HQ choices too.
I would agree with both Duff and Cog. Marines can outshoot Tau, and have bigger guns. Look, one lascannon in every squad, that's 6 lascannons, singularly, right? Then, as Duff suggested, a Dev. Squad of Missile Launchers and another of 4 heavy bolters. Possibly a squadron of Land Speeder tornadoes, too? That''s a lot of rending, AP4 shots. I myself, were I to fight another good Tau army would use my shiny new LSs. A squadron of three, one typhoon, one tornado, and one regular, to be used as the whipping boy. Maybe have them deep strike right behind his main body of fire warriors. Yes, their armour is weak, but 9 heavy bolter shots, 4 assault cannon shots, and a S5 blast weapon can't be easily ignored, you know. Did you know that combo I just mentioned only costs 200 points? Bikes are handy for claiming objectives, and yo could add an attack bike with a multi-melta to get close to the hammerhead, and blow it to hell.
However, the one army that you can't outshoot, whether in volume of shots, or effectiveness of shot is the Imperial Guard.
Good luck on beating him, as I said before.
You may not see us
But we'll be there
You may not feel us
But you will care
Your shots will not hit us
We are shapes in the mists
Blink and you'll miss us
For we are the Ghost Fists!
