The M28A2 Reduced-Range Practice Rocket (RRPR) is a U.S. 227 mm live training rocket for HIMARS and M270-family crews. Lockheed Martin describes it as a training rocket that can be fired at all U.S. ranges, while Army budget documents note its inert payload section, blunt nose, and reduced maximum range of about 15 km.
Army budget material identifies the RRPR as the live training rocket for HIMARS and M270-family launcher crews.
