(refiling into correct category with some additional damage) i have discovered that when using the oXq.663.1e Ocua Drone that when more then one are present if ordered to attack then called off (and sometimes if the target is destroyed) will start attacking each other and refuse to stand down generally resulting in the total destruction of the swarm. from what i can tell this may be the drones having been damaged by friendly fire then trying to repair each other but failing to switch to the "repair shots", that or it's the group association thing, regardless once the chain reaction starts it will not stop until one drone is left (or possibly all drones are destroyed)
