    PREFACE

    This Pamphlet provides guidelines for planning & layout design of a Baffle Range, a reduced danger area range for practice firing with small arms. A safe Baffle range results if and only if it is operated safely, the firers are controlled by the rules and safety policies and its fitness is maintained. Therefore recommendations regarding Baffle range construction design, maintenance, fitness certification, usage and safety audit are also included herewith. These guidelines/ recommendations are based on literature survey, feedback received on performance of already constructed Baffle ranges and extensive data generated through trials at TBRL in recent years.

    The 4 Es (Evaluate, Engineer, Educate, and Enforcement) must be used at every step during development and usage of a Baffle Range. The design guidelines/recommendations, safety rules and safety policies stated in this Pamphlet and in Pamphlet No.33, Infantry Training , Volume III, Range and Courses, Range Construction and Regulation (All arms) must be enforced on the Baffle range construction and usage so as to ensure required safety and service life. The attention of users is especially required in Part-4 of this pamphlet Baffle range operation & maintenance so as to ensure safe firing practices and longer service life for Baffle range.

    It is hoped that the users will find these guidelines helpful in planning Baffle ranges which are cost effective, while affording safer service.

    SECTION-I

    GENERAL

    1. Small Arms Firing Range is a live-fire training facility for practice firing with small arms. 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. 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. It must be free from buildings, roads, footpaths, etc. These ranges were not very safe and several accidents have been reported because free flight rifle bullet can travel up to 3 Kms.

    A TYPICAL CONVENTIONAL CLASSIFICATION FIRING RANGE

    Need of Baffle Range 2. The area required for a classification range with full danger area is around 500 acres which is quite huge. 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. Troops have to travel long distances for practice firing. 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. 3. 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, side walls, ground barriers, bullet catchers, stop butt etc) at specified locations, properly conditioned impact surfaces, regular upkeep of impact area and strict enforcement of safety rules/ precautions in the range. 4. 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. Keeping this in view, TBRL Chandigarh has been indigenously developing concept/layout design of a range with reduced danger area requirements, termed as Baffle range, as an alternative effective and safe facility for small arms practice firing. Policy 5. In view of increasing density of civilian population in and around Cantts, construction of Baffle range assumes greater importance with a view to avoid accidents and consequent litigation cases. Keeping in mind present commitments of army and likely pattern of

    operations, it has been agreed that construction of Baffle range up to 300m would meet training requirements of army. However, where possible, scope for extending the Baffle range up to 500m at a later date should be created. 6. In order to ensure timely action: (a) HQ Commands will project Baffle ranges in MWP. (b) QMG Br. will plan allotment of funds for each Command. (c) E-in-C Br. will monitor construction of each Baffle range from BOO stage onwards till

    completion. (d) DG MT will process the case to obtain In Principle approval for construction of

    Baffle ranges from MOD, and monitor progress of allotment of funds and construction of Baffle ranges on quarterly basis.

    (e) Board of Officers (BOO) detailed by concerned formation at a given site will invariably have a member from TBRL, Chandigarh.
