As a wise Cortex Commander said, the Tiger is a brick with a gun. Try snapping a brick in half.

The Tiger is a general purpose heavy tank. Sporting a decent weapon and significant armor, Tigers are perfect for breaking through heavy fortifications and leaking into enemy bases at high speed, all while soaking up substantial amounts of damage.

Keep them repaired with Graverobbers.

It is cheaper and more armored than its ARMADA counterpart but it deals little area-of-effect damage and has little range for a T2 unit. Group them with Banishers to make up for this weakness.
