An impressive demonstration video from the Czech defense firm Excalibur Army shows their 155mm L45 DITA self-propelled artillery system firing three rounds within seconds, and causing all rounds to impact simultaneously on a single target.

The simultaneous impacts are coordinated by calculating flight time based on trajectory and charge. More impressive than the impacts, though, is the speed in which the vehicle is able to set up, fire, and leave its firing point before the rounds even impact. Also of note, is that the artillery system vehicle only requires two personnel to operate.
