[Titanfall] Why don't they ever use Tanks?
gpt
Tanks do exist, but a Titan's sheer flexibility cannot be discounted in combat. Pilot engagements are quick and dirty affairs, where battlefield deployment must be as sleek and low drag as possible. A Titan can be dropped directly into action with little more than an ablative shield, while a tank requires a full scale vehicle dropship that is vulnerable to the fighters that inevitably find themselves over the battle.

A Titan brings with it the advantages of infantry while still having the durability and firepower of more conventional vehicles. They can dodge fire and directly support infantry units more effectively than a tank can. While a tank will have thicker armour and bigger guns, they can only be brought in during protracted engagements, and they can't just simply sidle into an alleyway for cover when under fire.
