Tom Clancy's H.A.W.X.

Support Elements are items which give you an advantage over your enemies. When you get a certain amount of points, the game randomly selects a support element to give to you. Every support element is relatively easy to obtain except for the EMP. It seems that some support elements have higher probabilities of being selected than others. This may explain why EMPs aren't very common. Keep at it and once you have used every support element once, this trophy is yours. Here are the support elements that you will need to call in:

Repair Drone (All Damage done to your plane is repaired and the plane has full health)

Altitude Limiter (Limits the altitude at which enemy planes can fly)

Radar (All enemies show up on your Map)

Radar Jamming (Disables enemy Radar)

Cannon Upgrade (Cannon damage increased + more ammo)

EMP Strike (An electro-magnetic pulse is sent out that temporarily disables all enemy planes)
