    Building a Rattan Weapon for SCA Youth Combat By Mistress Arianna of Wynthrope Baronial Youth Combat Marshall, Barony-Marche of the Debatable Lands This article demonstrates one way to make rattan weapons for SCA Youth Combat Division 2 and 3 fighters. It is not the only way, but weapons made this way have passed inspection by Kingdom and Society level Youth Combat Marshals and proven to be durable and functional. You will need the following supplies and equipment: • A piece of rattan between ¾” and 1” in diameter and appropriate in length for the weapon you wish to make. Weapon length should be proportional to the fighter. Great weapons have the following maximum length limitations: • Spear - 7.5’ • Pole-arms - 6’ - The striking edge shall not exceed 1/3 of the weapons total length. • Great sword - 6’ - No more than 18" haft (hilt). • 1” inner diameter pipe foam that is at least 3/8” thick and long enough for the desired weapon • Closed cell camp foam, any thickness from ¼” to ¾” • A roll of duct tape • A roll of electrical tape in a contrasting color to the duct tape • Scissors • A utility knife • For single-handed weapons, a shoelace or other cord for a lanyard • A ruler 1 STEP 1 – Making sure your rattan is properly sized Using a ruler, verify that your rattan is at least ¾” and no more than 1” in diameter. If it is too large, use a plane or draw knife to shave it down, then sand the entire shaft. If it is less than ¾” in diameter, do not use that piece of rattan.

  • Explosive Weapon Effectsweapon Overview Effects
    CHARACTERISATION OF EXPLOSIVE WEAPONS EXPLOSIVEEXPLOSIVE WEAPON EFFECTSWEAPON OVERVIEW EFFECTS FINAL REPORT ABOUT THE GICHD AND THE PROJECT The Geneva International Centre for Humanitarian Demining (GICHD) is an expert organisation working to reduce the impact of mines, cluster munitions and other explosive hazards, in close partnership with states, the UN and other human security actors. Based at the Maison de la paix in Geneva, the GICHD employs around 55 staff from over 15 countries with unique expertise and knowledge. Our work is made possible by core contributions, project funding and in-kind support from more than 20 governments and organisations. Motivated by its strategic goal to improve human security and equipped with subject expertise in explosive hazards, the GICHD launched a research project to characterise explosive weapons. The GICHD perceives the debate on explosive weapons in populated areas (EWIPA) as an important humanitarian issue. The aim of this research into explosive weapons characteristics and their immediate, destructive effects on humans and structures, is to help inform the ongoing discussions on EWIPA, intended to reduce harm to civilians. The intention of the research is not to discuss the moral, political or legal implications of using explosive weapon systems in populated areas, but to examine their characteristics, effects and use from a technical perspective. The research project started in January 2015 and was guided and advised by a group of 18 international experts dealing with weapons-related research and practitioners who address the implications of explosive weapons in the humanitarian, policy, advocacy and legal fields. This report and its annexes integrate the research efforts of the characterisation of explosive weapons (CEW) project in 2015-2016 and make reference to key information sources in this domain.

  • Ethical Issues in the Global Arms Industry
    draft: March 7, 2015 Michael Davis, Illinois Institute of Technology Ethical Issues in the Global Arms Industry: A Role for Engineers Ethical Dilemmas in the Global Defense Industry Conference University of Pennsylvania Law School Philadelphia, April 16, 2015 This paper has four parts. The first two seek to clarify the subject of this conference, ethical issues in the global arms industry. The third sketches the role engineers have in much of the global arms industry. The last part considers one way that engineers might help with resolving some of the industry’s ethical issues. While the first part of this paper should contain few surprises, the last three will, I hope, contain more. 1. Dilemmas and Defense Let me begin with two differences between the official title of this conference and the title of my paper. First, I have substituted “issues” for “dilemmas”. Second, I have substituted “arms” for “defense”. The purpose of these changes is to avoid unnecessary disputes rather than to change the subject of the conference. Let me explain. A “dilemma” is a situation in which a difficult choice has to be made between two (or more) equally undesirable alternatives.1 If the alternatives were not equally undesirable, the choice would be easy: choose the more desirable alternative. There would be no dilemma (though the choice might, like most good choices, have its cost). My impression is that the main ethical issues, questions, problems, or quandaries posed by the global arms industry are not dilemmas (in this sense) but complex situations in which most of the choices on offer are hard to assess and many of the best choices have yet to be devised.

  • Fighting Vehicle Technology
    Fighting Vehicle Technology 41496_DSTA 60-77#150Q.indd 1 5/6/10 12:44 AM ABSTRACT Armoured vehicle technology has evolved ever since the first tanks appeared in World War One. The traditional Armoured Fighting Vehicle (AFV) design focuses on lethality, survivability and mobility. However, with the growing reliance on communications and command (C2) systems, there is an increased need for the AFV design to be integrated with the vehicle electronics, or vetronics. Vetronics has become a key component of the AFV’s effectiveness on the battlefield. An overview of the technology advances in these areas will be explored. In addition, the impact on the human aspect as a result of these C2 considerations will be covered. Tan Chuan-Yean Mok Shao Hong Vince Yew 41496_DSTA 60-77#150Q.indd 2 5/6/10 12:44 AM Fighting Vehicle Technology 62 and more advanced sub-systems will raise the INTRODUCTION question of how the modern crew is able to process and use the information effectively. On the modern battlefield, armies are moving towards Network-Centric Warfare TECHNOLOGIES IN AN (NCW). Forces no longer fight as individual entities but as part of a larger system.

  • DIRECTED ENERGY DEVICES Directed Energy Weapons, Also Known by the Brand Name Active Denial System, Are a New Technology Developed by the U.S
    DIRECTED ENERGY DEVICES Directed energy weapons, also known by the brand name Active Denial System, are a new technology developed by the U.S. military. This technology delivers very high-frequency millimeter-wavelength electromagnetic rays that heat skin on contact, causing a painful burning sensation. These weapons have not been used on protests to date but are actively in development for crowd-control purposes, and they are being marketed to law enforcement as well as military agencies. HISTORY The U.S. Air Force Research Laboratory and the U.S. Department of Defense’s Joint Non-Lethal Weapons Directorate initially funded the development of an electromagnetic heating weapon in 2002. By 2004, private manufacturers such as Raytheon were funded to continue research. The first prototype, Active Denial System I, underwent some testing and was deployed in Afghanistan in 2010, but was recalled a few months later and has never been used since then against enemy combatants in military settings. Since 2011, the updated ADS II and the Silent Guardian, a smaller mobile device, have been demonstrated on military personnel and volunteers. The Silent Guardian is marketed directly to civilian law enforcement agencies and other security providers. Directed energy weapons project a focused beam of electromagnetic waves at a high frequency HOW THEY WORK and short wavelength, making them capable of penetrating superficial skin layers to cause pain and burning without causing ionizing radiation that can alter cellular structure. The electromagnetic beam is invisible and can travel distances of up to one kilometer. There are truck-mounted versions and a newer, more transportable version being considered.

  • Teachers' Guide for Military Technology
    Military Technology TO THE TEACHER OBJECTIVES OF THIS UNIT: To help students think about warfare from the perspective of the technology used, thus linking military history to economic history and the history of science. TEACHING STRATEGIES: This unit can be used to help students grasp the long-term military confrontation between Chinese dynasties and the northern steppe societies. This unit lends itself to a comparative approach as many of the weapons and techniques have close counterparts in other parts of the world. Most of the images in this unit were taken from wood block illustrations in traditional Chinese books. To make this unit more challenging, teachers could raise questions about the advantages and limits of such sources. WHEN TO TEACH: Although the material in this unit derives primarily from Song dynasty sources, it deals with weapons and defensive systems in use for many centuries, and even in a chronologically-organized course could be used earlier or later to good effect. If used as part of instruction on the Song period, students would get more from the unit if they have already been introduced to the struggle between the Song and its northern neighbors, culminating with the Mongols. This unit would also be appropriate for use in teaching comparative military history. The Song period is a good point to take stock of China's military technology. First, warfare was central to the history of the period. The confrontation between the Song and the three successive non-Chinese states to the north (Liao, Jin, and Yuan) made warfare not only a major preoccupation for those in government service, but also a stimulus to siegecraft crossbows and rethinking major intellectual issues.
