If I did Tau, then it would be something like this:
Tau "Fivetide" - 2,000 points
HQ
Commander Farsight
O'Vesa
Elite
Riptide - ion accelerator, talisman of arthas moloch, twin-linked fusion blaster, early warning override and target lock

3 x Crisis Suits - 2 x missile pods, 2 x missile pods, 2 x fusion blasters and target lock
Fast Attack
4 x Pathfinders
4 x Pathfinders
Tau Allies
HQ
Commander - command and control node, multi spectrum suite, puretide engram neurochip and iridum armour
Elites
Riptide - twin-linked fusion blaster, early warning override and velocity tracker
Troops
10 x Kroot Carnivore Squad
Fast Attack
4 x Pathfinders
Total: 1,994
O'Vesa, buff commander and the iontide join to make a shooty deathstar. The unit is rerolling to hit, ignoring cover and will have monster and tank hunter. They can deal with flyers ok thanks to early warning override giving interceptor. The iontide can split fire thanks to target lock.
The rest just shoot things to bits; sniper kroot take wou ds off monstrous creatures, farsight drops in and nukes camping vehicles and hassles camping units. The kroot with the hound can sneaky on an objective or grab linebreaker.
