I didn't see any of the action, having purposefully removed myself from the viewscreens at Dad's suggestion, but I knew what was happening. Our laser equipped drones swung in behind the enemy forces as they crossed the border. Once they were all across, we targeted those in the rear, lasers neatly severing the brainstem through the base of the skull. They dropped without a sound. Since those in front of them were focused on their advance, they mostly didn't notice anything was wrong until it was their turn. Some few looked back and saw their fellows dropping, but it was late in the effort and there was nothing they could do anyway. The area would be littered with bodies. No blood, except those few who smashed their faces when they fell, even then there wasn't much because their hearts had already stopped beating before they hit the ground.
