With long range and good ranged damage, but low health and even lower melee damage, the Tau can be considered to be glass cannons. They combine good mobility and offensive power but suffer from weak melee that mean they need to be protected by auxiliary forces. Their vehicles also have good mobility with the ability to jump and most have long range but are fragile. Their defenses also tend to be on the fragile side.
