Tactical training round

A Tactical Training Round is a round used to simulate live fire.

Background
The TTR round 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.

The rounds are known to be used in MA5B ICWS Assault Rifles, M6 Magnum Sidearms, SRS99C-S2 AM Sniper Rifles, and BR55 Battle Rifles

Trivia

 * The paint is said to have a sweet smell to it.
 * If the paint hits an object and splatters on someone, they can still be paralysed.
 * The paint can be adapted to be used in claymores.
 * The proximity fuse will stop you from firing through a narrow gap or chain-link fence. Thus, in training you could stand in the open and, as long as your opponents are on the other side, you are safe.
