Troops have to travel long distances for practice firing. regular upkeep of impact area and strict enforcement of safety rules/ precautions in the range. etc. roads. These ranges were not very safe and several accidents have been reported because free flight rifle bullet can travel up to 3 Kms. There is an overall shortage of classification ranges primarily due to non availability of adequate and suitably situated land for constructing safe and efficient ranges. In view of increasing density of civilian population in and around Cantts. A TYPICAL CONVENTIONAL CLASSIFICATION FIRING RANGE Need of Baffle Range 2. Small Arms Firing Range is a live-fire training facility for practice firing with small arms. TBRL Chandigarh has been indigenously developing concept/layout design of a range with reduced danger area requirements. The danger area provides a safe zone for the misdirected bullets resulting from possible errors made by soldiers in both horizontal and vertical directions during practice firing.RESTRICTED SECTION-I GENERAL 1. construction of Baffle range assumes greater importance with a view to avoid accidents and consequent litigation cases. as an alternative effective and safe facility for small arms practice firing. The requirement of danger area for classification ranges can be reduced up to 20 acres by providing suitably designed ballistic protection structures (such as baffle walls. 3. Therefore it has become necessary to explore an alternative means whereby land requirement for classification ranges can be minimized and yet the firing practice is carried out without compromise. 4. side walls. properly conditioned impact surfaces. footpaths.

Keeping in mind present commitments of army and likely pattern of BAFFLE RANGE PROCEDURES TBRL / PAMPHLET / BR01/ 2006. ground barriers. It must be free from buildings. Such a great saving of land creates a possibility of having practice firing ranges at cantonments with short availability of land due to increasing population and very high estate cost. Conventional Classification Ranges (CCR) used for firing practice with small arms are provided a danger area extended up to 1830 m behind the stop butt. RESTRICTED Sheet 1 of 21 . The area required for a classification range with full danger area is around 500 acres which is quite huge. work on Baffle ranges has been sanctioned. An evaluation committee comprising representatives of QMG. HQ commands will forward a consolidated report to Army HQ/MT-5 giving only the relevant points.

PART-6 GLOSSARY . Firing Range: A facility designed for the purpose of providing a place on which to discharge firearms. Noise: Unwanted sound is referred to as noise. Chamber: The enlarged portion of the barrel at the breech in which the cartridge is placed ready for firing. and designed to capture ricocheting projectiles. Firing Line: A line parallel to the targets from where firearms are discharged. Baffles: Barriers to contain bullets and to reduce. Barrel: The metal tube of a gun made from iron or steel. or on the range floor. or as a protective or dividing wall between ranges. The case is usually made from brass but may be steel. Direct Fire Zone: The area between stop butt and most distant firing line. Bullet: A single projectile fired from a firearm. Criteria for elimination of ricochet from ground The ricochets from ground can be eliminated by ensuring bullet impacting soft soil at an angle exceeding 30deg. shoot air guns and/or archery equipment. and also the requirement of ground slope is minimized. More frequently used on backstop areas where the slope does not positively contain bullets. Copy: 06. The term may also refer to an area down range of a Baffle range from first firing point towards stop butt where bullets will impact. a berm. • minimum maintenance requirements for shape of ground barriers. Muzzle Velocity: The velocity of a projectile as it exits the muzzle of a firearm. Berm: An embankment used for restricting bullets to a given area. Cartridge: A self-contained unitized round of ammunition that is made up of a case. if appropriate. an instructor. redirect or suppress sound waves. Bullet Trap: A device designed to trap or capture the entire bullet and fragments as opposed to redirecting the projectile into a sand pit. • height of ground barriers must not interfere with bullet trajectory and allows easy movement of soldiers.RESTRICTED SECTION-XI DEFINITIONS Backstop: A device constructed to stop or redirect bullets fired on a range. Line of Sight: An imaginary straight line from the eye through the sights of a firearm to the target. metal alloy or plastic. powder and a bullet. Horizontal Bullet Catcher (Eyebrow Catcher): A device installed along a backstop. Firing Range Complex: It may include offices. Firing Position (Point): An area directly behind the firing line having a specified width and depth that is occupied by a firer.

The absorption of bullets misdirected towards ground can be achieved by constructing ground barriers ahead of firing point satisfying following requirements • minimum possible number of ground barriers must be used. Baffles are placed either overhead. Firing Distance: The distance between the firing line and the target line. parking facilities and other related structures. Impact Area: That area in a backstop or bullet trap directly behind the target where bullets are expected to impact. club houses. Oct 2006. and a secondary danger area. Copy: 06. 45 degrees or less. an impact area. Safety Baffles: Vertical or sloping barriers designed to prevent a projectile from traveling into an undesired area or direction. Venetian Blind Trap: A steel trap that has a series of angled plates. Target Line: A line parallel to the firing line along which targets are placed. Rules and regulations are set up to govern the method of range operation to include health and safety. The SDZ may also include a weapon back-blast area. handguns (pistols). rifles up to 7. Oct 2006. BAFFLE RANGE PROCEDURES TBRL / PAMPHLET / BR01/ 2006. Small arms are not subject to precise definitions. Small Arms: Firearms that may be both carried and discharged by one person.RESTRICTED Rules and Regulations: Standards used in the operation of a firing range. The chamber provides easy access for lead removal. shotguns. a ricochet trajectory area. Most often used to prevent bullets from leaving a confined area. as opposed to artillery pieces. The SDZ includes the area between the firing line and the target line. The violation of range rules and regulations generally carries penalties enforced by range officer. The SDZ must be located completely within the boundaries of Armed force -owned or -leased properties. The height of the VDZ varies with the weapon and ammunition fired. but the term usually includes rifles.62mm. and certifying personnel in the use of handguns. submachine guns and machine guns. where remaining velocity and energy are expended. Surface Danger Zone (SDZ): The portions of the range in the horizontal plane that are endangered by firing a particular weapon. Small Arms Range: Small Arms Firing Range is a live-fire training facility for practice firing with small arms to improve the marksmanship skills of soldiers. Vertical Danger Zone (VDZ): The VDZ is the volume of airspace above the SDZ between the ground surface and the maximum ordinate of a direct-fired or ricochet round. The bullets are directed upon impact into a chamber located at the bottom of the device. Trajectory: The path a projectile travels from the muzzle to the point of impact.
