A carbine from French carabine, is a long arm firearm but with a shorter barrel than a rifle or musket. Many carbines are shortened versions of full-length rifles, shooting the same ammunition, while others fire lower-powered ammunition, including those designed for pistols. The smaller size and lighter weight of carbines makes them easier to handle.
They are typically issued to high-mobility troops such as special-operations soldiers and paratroopers, as well as to mounted, artillery, logistics, or other non-infantry personnel whose roles do not require full-sized rifles, although there is a growing tendency for carbines to be issued to front-line soldiers to offset the increasing weight of other issued equipment. An example of this is the US Army’s M4 carbine, which is standard-issue.
Indoor ranges usually have a back wall with a sloped earthen berm or bank, with reinforced baffles additionally situated along the roof and side walls. Ranges with proper ventilation pull smoke and lead particles away from the shooting line and discharge them from the building to reduce potential lead poisoning. When ranges lack proper ventilation, employees and users are exposed to lead dust from bullets or cartridge primers. It can be inhaled or can settle on skin or clothing.
