Point A
This point is very defensible. If you stay near it, enemies will have a hard time getting close. Place an S-Mine 44 or a Satchel Charge directly on the point to make defending it that much easier. You’ll want at least one teammate near the area to help you defend it, but watch out for positions that put you in the line of sight of any enemies on top of the Gustav. If you get behind cover and have a good view of the area surrounding the point, you’ll have an easy time defending it.
Point B
The major area of contention will be point B, which is placed firmly in the center of the Gustav. There are only two paths onto the Gustav and both are easily defended if you have teammates. Watch out for Scorestreaks and enemies with good grenade-throwing arms, but you’ll have the upper hand when attacked directly. Of course, this rule works both ways. If the enemy team can take and entrench themselves on top of the Gustav, you’ll have your work cut out for you. Use grenades and the Glide Bomb/Artillery Barrage Scorestreaks to help dislodge the enemy. If those options aren’t available, you’re better off trying to hold both Points A and C and ignoring Point B. While Point B is exceedingly defendable, it’s just as easy to lock players up on top of it, given the lack of ways off and on it.
Point C
The point that is closest to your starting position at the beginning of the round is the easiest to defend. There’s plenty of cover here and you can use the Barn’s upper floor to see enemies coming from a mile away. Watch the side paths for sneak attacks, but you’ll have the upper-hand while defending this point in nearly every fight, provided you stop the sneak attacks. Take note: This map is big enough that someone will need to remain near this point at all times, or you’ll risk losing it to the enemy.
