IMHO it's overrated. Strictly map mode, no first person fighting per se. You give orders and have the ability to use perks(use UAVs, disable enemy radar, relay item drops, promote squads etc) to help your team during the battle. Whether or not people follow your orders is an entirely different matter. Can see it being useful if you are in pre-mades where the information can be relayed via mic to the rest of your team to avoid back caps or being flanked.
