The T'au do not have any psykers nor units that specialize in countering psykers, which makes them somewhat more vulnerable to psychic attacks. While most armies in 40k may only make a single overwatch action a turn, Tau have no such limitation, and may even have units fire overwatch for close by allies. They heavily use the Overwatch special rule, which allows them to shoot back at their enemies when charged, with devastating power.
They have some of the most powerful ranged weaponry in the game in terms of both range and stopping power. The T'au specialized in ranged warfare and die quickly in melee.
