Tactical training round

From Halopedia, the Halo wiki

A Tactical Training Round is a round used to simulate live fire. It has a plastic polymer shell that helps maintain the actual characteristics of bullet flight. Inside there is a proximity fuse that dissolved its shell when the round comes within 10 cm of surface. Once dissolved, a blob of red paint splatters through the air. The paint also hides a powerful anesthetic and immobilizes the nanofibers woven into clothing causing it to harden. The target then loses the ability to move the hit body part, simulating a bullet wound to the area. The rounds are known to be used in MA5B Assault Rifles, M6D sidearms, and BR55 rifles.[1]
