Pathfinder Specialization: Spartan optimization for deep, unconventional deployment within unknown enemy territory and with little to no assistance from command.

Gunner Armor Mod: The Gunner armor mod decreases the time of weapon overheat when occupying a vehicle weapon position and increases Spartan speed while carrying a detached turret.

The Gunner armor mod - which was designed to explore alien worlds - has two major functions: One, when you're on a mounted anti-infantry gun (Warthog and the secondaries of Wraith, Scorpion, etc.), the guns overheat less quickly, allowing you to fire longer at the maximum rate of fire. And two, when you pull the gun off an emplaced mount, you move faster, allowing you to use those guns more effectively offensively instead of just defensively. You still won't be able to use Armor Abilities or Sprint, but you can move faster, bringing some heavy firepower to any offensive attack.
