Making a unit attack from behinde ?

Ive made an air unit, it has a frontal ground attack
but for air i dont want it to turn around and face to face with the target but to fired from the back, how is this possible ?

I think it would have something to do with model editing actually. You will need to redo the animation too if you need to edit the model.

the only units that don't rotate while being attacked are towers or structures i think. maybe it can be done.
