Strategies:-
The Eagle is a flying war ship with strong armor. Using its missiles, it can quickly destroy enemy ground and air units. Though rather slow, with Afterburners and such, it can fly faster than an average owl. It can be used to support other ground units, preventing them from being killed by other ground units or AG units. The Eagle, can also be used to support air units like Rocs or Albatross, drawing the attention away from the Rocs.

Support:-
With adequate armor and HP, the Eagle can be a deadly enemy to face. With its continuous rain of missiles and lasers, anything that gets in the way can be destroyed easily. The trick to using an Eagle is speed. If you can't catch the enemy, there goes or food. So a good power supply (methane or anything better) and a normal afterburner should to the trick. Once your Eagles can fly fast, it will be a breeze. Just afterburn your way in, kill as much as you can and afterburn out again as soon as something can hurt you tremendously. Another trick is to fly the most injured Eagle away from the enemy, making the enemy follow the injured Eagle. Thus, the rest of your Eagles can pick them off while the attention is being drawn away.
