I'd be sending me some 'rad gun bunnies downrange to replace my targets. Those guys must have been about as popular as the small pox with your target detail.
The best part was the *moving tank* targets, pulled by a steel cable. If the 155HE rounds hit just a bit low, they cut the multiple tow cables to shreads. Of course, they wouldn't have done a light armored vehicle, and probably not a tank, a whole lot of good either. I saw an old French M24 light tank take a near hit from a 155 HE round; it just disappeared in all directions.
