Little Bird passenger with a grenade launcher in the front seat

This entire strategy defeats the purpose of locking the other stuff behind 20 points. You can't build a FOB without getting instantly grenade-spammed, and then the Humvees come in.

If they had to sit in the side seat, aiming would at least require some skill. But this way they're protected, and a good pilot can just line up the gunner on people.

I've had this happen in two games in a row. The choice shouldn't be between building AA or even a wall first.
