Useful in so many situations so long as you still have access to ammunition....
And so long as the enemy can be brought down with shut gut ammo.
For things like Uavs like "big dog" or "Predator" a coil gun might be better suited....
So long as one has the electricity needed... and solar thermal is a super cheap way of getting the electricity needed to fire useful reliable coil guns...
