of much lower density than the lead normally used in bullets, are larger, and are fired at lower velocities. Rounds are designed with low mass, moderate velocity, and large surface area to prevent the rounds from penetrating the skin significantly or causing severe injury, so they merely provide a painful blow to the target: but instances have been reported where rubber or plastic bullets have caused significant injuries to the body or eyes, and in some cases caused death. One broad classification of impact rounds is direct fire and indirect fire rounds. Direct fire rounds can be fired directly at the target, ideally targeted low on the target, away from vital organs that are more prone to damage from the impact. Baton rounds Baton rounds, often called rubber bullets or plastic bullets, are cylinders made of rubber, plastic, wood, or foam, and can be as large as the full bore diameter of the launcher. Smaller baton rounds may be encased in a shell casing or other housing. Baton rounds may fire one long baton, or several shorter batons. Harder or denser baton rounds are intended for skip fire, while softer or less dense batons are intended for direct fire. Baton rounds are the subject of significant controversy, due to extensive use by British and Israeli forces, resulting in a number of unintended fatalities. Beanbag rounds Beanbag rounds consist of a tough fabric bag filled with birdshot. The bag is flexible enough to flatten on impact, covering a large surface area, and they are used for direct fire. Beanbag rounds may be wide and flat, designed for close range use, or elliptical in shape, with a fabric tail to provide drag stabilization, for longer range use. Rubber buckshot These, also called stinger rounds, consist of a number of rubber balls ranging from around in diameter, and are used for direct fire. The small diameter means that each ball contains far less energy than a baton round, but it also limits the range. Rubber slugs, used in 12 gauge firearms, consist of a fin stabilized full bore diameter rubber projectile. These are used for long range, accurate direct fire shots on individual targets. Pepperball rounds Pepper-spray projectiles, commonly called pepperballs, are direct-fire paintball-like capsules filled with a pepper spray solution of capsaicin. They provide a longer range, more user-friendly way to disperse pepper spray. Many sorts can be fired from paintball markers.
