If you prefer playing an anti-aircraft role, the better choice for a suit may be the Flak Armor certification. The Flak Armor certification reduces the amount of damage taken from explosives. Most vehicles and aircraft will be using explosive ammo and therefore in the anti-vehicle role this suit will be more important.

In addition to the Flak Armor, purchasing a second Burster for your MAX is highly recommended, essentially doubling your efficiency against aircraft.
