A Tactical Training round (TTR) is a round used to simulate live fire.
The TTR has a plastic polymer shell that helps maintain the actual characteristics of bullet flight. Inside, there is a proximity fuse that dissolves the shell when the round comes within 10 centimeters of a surface. Once dissolved, a blob of red paint splatters onto the target. The paint also hides a powerful anesthetic and immobilizes the nano-fibers woven into clothing, causing it to harden. This is used for training simulations. The target then loses the ability to move the body part that is hit, simulating a bullet wound to that area. The rounds also have a tranquilizing effect caused by the anesthetic, essentially paralyzing (or close to it) whatever body part they hit for a short time. The anesthetic in the paint can also knock someone unconscious for up to a few hours, depending on where they are shot.
They were used by the Harvest Militia, ODST, and Corbulo Academy of Military Science cadets for training purposes.
- Lieutenant Commander Jilan al-Cygni used two TTR shots to knock Governor Nils Thune unconscious and end his resistance to the evacuation plan for Harvest during the First Battle of Harvest.
