Ballistics is a comprehensive treatise on the science of projectiles, originally prepared by James Monroe Ingalls under the authority of the United States Adjutant-General's Office. This detailed work explores the principles governing the motion of projectiles, offering insights into the mechanics of gunnery and ordnance. Covering both theoretical aspects and practical applications, "Ballistics" provides a thorough understanding of the factors influencing projectile trajectory, velocity, and impact.
