"They have to come close to the ground to fire with any accuracy," Cissel explained, her voice dropping into a fierce tone.
"On top of that, every time they execute an attack, they are forced to circle back into the high atmosphere before they can dive again.
You see, their targeting sensors are calibrated for high-altitude scanning; if they stay low for too long, their tracking sensors will keep locked at the same spots they targeted before falling.
Also, once they lock on fixed targets, not moveable ones like us. Their sensors can't move and track the targets if they dart away from their fire. If they don't reset their sensors by going up, they'll keep firing at the spots they locked, even if the target has moved, ending up showering the dirt with wasted laser fire."
"..."
The meaning behind her words was clear. Even if these flying drones were terrifying, they weren't invincible. They were very limited by the inefficiency of their sensors, just like how Cissel described.
