A pretty simple request: make the .target modifiable. This would help especially in dead six gunnery practice. A player could get very precise feedback on how far up or down to aim to get the appropriate bullet drop at various ranges. As it is now, it's rather difficult to know how an enemy will look at the .target ranges and also difficult to estimate the center (i.e., what you are actually aiming for).
Edit: yes there are drones, but they do not provide dead six shots. Dead six practice is all I'm really asking for here, it's far too difficult to catalog all the possible deflection shots.
