Training Circular (TC) 3-09.81, "Field Artillery Manual Cannon Gunnery," sets forth the doctrine pertaining to the employment of artillery fires. It explains all aspects of the manual cannon gunnery problem and presents a practical application of the science of ballistics. It includes step-by-step instructions for manually solving the gunnery problem which can be applied within the framework of decisive action or unified land operations. It is applicable to any Army personnel at the battalion or battery responsible to delivered field artillery fires. The principal audience for ATP 3-09.42 is all members of the Profession of Arms. This includes field artillery Soldiers and combined arms chain of command field and company grade officers, middle-grade and senior noncommissioned officers (NCO), and battalion and squadron command groups and staffs. This manual also provides guidance for division and corps leaders and staffs in training for and employment of the BCT in decisive action. This publication may also be used by other Army organizations to assist in their planning for support of battalions. This manual builds on the collective knowledge and experience gained through recent operations, numerous exercises, and the deliberate process of informed reasoning. It is rooted in time-tested principles and fundamentals, while accommodating new technologies and diverse threats to national security.

This is a detailed survey, replete with photographs and diagrams, of the field artillery used by both sides in the Civil War. In paperback for the first time, the book provides technical descriptions of the artillery (bore, weight, range, etc.), ordnance purchases, and inspection reports. Appendixes provide information on surviving artillery pieces and their current locations in museums and national parks.

This publication, Army Techniques Publication ATP 3-09.50 MCWP 3-1.6.23 The Field Artillery Cannon Battery July 2015, provides doctrinal guidance for commanders and subordinate leaders who are responsible for conducting cannon battery functions or tasks. It serves as an authoritative reference for personnel responsible for developing: - Doctrine (fundamental principles; tactics, techniques, and procedures) material and force structure. - Institution and unit training. - Tactical standard operating procedures for cannon battery units. ATP 3-09.50 reflects and supports unified land operations doctrine contained in Army doctrine publication 3-0 and Army doctrine reference publication (ADRP) 3-0. ATP 3-09.50 contains 12 chapters and 4 appendices: - Chapter 1 provides an overview and discussion of cannon unit organization and tactical duties of key personnel. The chapter discusses the transition from 2 firing batteries of 8 howitzers each to 3 firing batteries of 6 howitzers each in all brigade combat teams and the introduction of composite (mixed-caliber) battalions in Infantry brigade combat teams. - Chapter 2 discusses considerations for employing a cannon battery in various climates and terrain. - Chapter 3 provides an overview and discussion of techniques and associated considerations for reconnaissance, selection, and occupation of a firing position. - Chapter 4 considers techniques for laying the platoon or battery, and measuring and reporting data associated with the gunnery solution. The chapter covers use of the gun laying and positioning system, M2A2 aiming circle, M2 compass, and reciprocal laying by other howitzers. - Chapter 5 provides an overview and discussion of techniques and associated considerations for battery defense against armored or mechanized forces, air attack, dismounted attack, indirect fire, and chemical, biological, radiological, and nuclear attack. - Chapter 6 identifies the techniques and associated considerations for hasty survey. - Chapter 7 discusses the types, elements, and sequence of fire commands. - Chapter 8 provides a summary of the steps for computing minimum quadrant elevation. - Chapter 9 provides an overview and discussion of other considerations unique to composite units. - Chapter 10 provides a brief overview and discussion of techniques and associated onsiderations unique to cannon batteries operating as distributed units. - Chapter 11 discusses other considerations for cannon batteries operating as composite or distributed units - training, battery tasks, sustainment, communications, fire support, survey, and meteorological tasks. - Chapter 12 Identifies planning considerations associated with deployment as early as possible in the military decision making process. - Appendix A provides techniques and associated considerations for precision munitions and ammunition management. - Appendix B identifies sample mission checklists. - Appendix C addresses techniques and associated considerations for overcoming common mistakes and malpractices. - Appendix D provides examples and discussion of required forms. - Appendix E discusses the declination of the aiming circle and the M2 compass. - Appendix F describes the employment of Killer Junior - the use of high explosive direct fire against dismounted attacks.
