A weapon, arm, or armament is any device used with intent to inflict damage or harm to living beings, structures, or systems. Weapons are used to increase the efficacy and efficiency of activities such as crime, law enforcement, self-defense, and warfare. In a broader context, weapons may be construed to include anything used to gain a strategic, material or mental advantage over an adversary. While just about any ordinary objects such as sticks, stones, cars, or pencils can be used as weapons, many are expressly designed for the purpose - ranging from simple implements such as clubs, swords and guns, and to complicated modern intercontinental ballistic missiles, biological and cyber weapons. This book has been written keeping in view the requirements of undergraduate and postgraduate students and research scholars in the area of weapons and warfare and Military history.
