War is an objective-based game mode with multiple objectives to complete or prevent from being completed, depending on which side of the conflict you’re on. If you’re attacking, your job is to complete objectives until you’ve taken the territory and won the round. As the defender, you must prevent attackers from accomplishing their goals at every turn. During most games of War, you’ll find that one side does the attacking while the other side does the defending, but this is definitely not exclusive. There are times where the roles will reverse on an objective and your job will be the opposite of what you might have expected.
Regardless of which side you’re on, the timer for each objective is short and the gameplay tense. The objectives are fixed on each map, so read through this section of the book to learn about each objective beforehand; it will go a long way in keeping you from getting caught with your pants down once a proper War match begins.
One last note about War: Scorestreaks are not allowed. You must fight just like your grand pappy and his pappy before him. You’ll find some Scorestreaks (such as the Flamethrower) in Care Packages that are occasionally dropped onto the map, but you should go in expecting to only find support from your firearm and your comrades on the battlefield.
