Someone posted on here in some thread a while back on what each specilization includes. I just hit level 60 and want to be more choosy for my next one. So does anyone know what perks they unlock. I just did Pathfinder so I know it unlocks the Gunner support
upgrade which allows you to move quicker while manning a detached turret and lengthens the ability to fire a manned turret without needing to cool down as you would normally.
