Small caliber dummy, drill, and inert ammunition The dummy, drill, and inert (DDI) cartridges are designed to aid in easy identification of inert ammunition to prevent injury caused by any mix-up with live service ammunition during training. The DDI are completely nickel plated with the 9mm DDI having two holes drilled in the cartridge case, while the 5.56, 7.62, and .50 caliber DDI have fluted cartridge cases to aid tactile identification in darkness. For the Army, the nickel plated DDI will be the only DDI inert small caliber cartridges authorized for classroom training and weapon cycling functioning for weapon maintenance, or other situations when inert cartridges are needed.
