If you’re shooting at someone, it is highly likely that they will try to avoid getting hit. Ergo, for people who sometimes shoot at other people as part of their job—like the Marines, for instance—one might expect a certain level of training involving moving targets. Not so fast!

According to a report in the Marine Corps Times, the military’s Semper Fidelis contingent is finally adding moving targets to its list of marksmanship qualifications. Soon, in addition to stationary targets, Marines will also need to know how to successfully gun down a mobile object.

The precise training method is still in development—the request was reportedly made to the Weapons Training Battalion in October, and made public in February—but apparently Marines have been talking about their lack of success with moving targets “for years.”

The actual practical implementation of a training method, however, is a tad more complicated. There are a few shooting ranges right now that serve as testing sites for moving targets, but they’re expensive because of the targets themselves: ROBOTS!
