Baton round

Baton rounds, also known as kinetic impact projectiles (KIPs), are a less lethal alternative to traditional bullets. Baton rounds are designed to impact rather than to penetrate and are typically used for riot control.

Common types of baton round have included the:


 * Bean bag round, a less-lethal projectile fired from a normal 12-gauge shotgun
 * Plastic baton round or plastic bullet, a less-lethal projectile fired from a specialised gun
 * Rubber baton round, commonly called the rubber bullet, a rubber-coated projectile with a metal or ceramic core.
 * Wooden baton round (which are meant to be skipped off the ground into the targeted area), also called a wooden bullet (a bullet is a direct impact round).
 * Foam baton round, also called a sponge grenade

Such munitions are meant to cause pain and incapacitation but not penetrate flesh. However, baton rounds can cause death and serious injuries such as damage to internal organs, permanent disabilities including blindness, especially when fired from close range at the head, neck, chest, or abdomen.

History
The use of baton rounds dates back to the 1880s, when Singapore police fired sections of broom handle at demonstrators in Singapore. The Hong Kong police subsequently developed wooden baton rounds, but they were likely to splinter and cause wounds.

Rubber bullets were invented by the British Ministry of Defence for use against rioters in Northern Ireland during The Troubles, and were first used there in 1970.

Rubber bullets tend to bounce uncontrollably, and have largely been replaced by other types of baton rounds, including plastic bullets: solid PVC cylinders 10 cm long, 38 mm in diameter, and weighing 135g. They were invented by Porton Down scientists and intended for use against rioters in Northern Ireland, first used there in 1973.

Injuries
In a 1975 study of injuries in 90 patients injured by rubber bullets, 1 died, 17 suffered permanent disabilities or deformities and 41 required hospital treatment after being fired upon with rubber baton rounds. A review of studies covering multiple different munition types/designs, which covered 1,984 people injured by "kinetic impact projectiles" and found that 53 died, plus 300 permanently disabled. Baton rounds can cause blindness as shown by their use by police in the 2019-2020 Chilean protests. During the first 3–4 months of protests in Chile, rubber bullets contributed to have a toll of 427 persons with eye injuries, an extremely high number when comparing to other protests or conflict zones in the world.
