Anonymous, Lectures on Land Warfare; A tactical Manual for the Use of Infantry Officers
“ CHOOSING A POSITION.—The framework of the modern defence consists of artillery and machine guns; into this framework are fitted the defence posts or defended localities garrisoned by infantry, who are responsible for holding their ground at all costs and for inflicting the greatest possible loss on the enemy. A commander will require a position which affords elasticity for increasing the resistance as the attackers penetrate the defences, and depth will thus be essential. ”
