However, combats last longer nowadays, and the shock action of Frederick the Great's tactics is no longer practicable. The fight is carried on at longer ranges, and the tremendously costly decisive moments of the past are of rarer occurrence. As a consequence, the casualties of the whole force engaged are smaller, although, owing to unfavorable conditions, certain organizations may suffer losses quite as great as those incurred in the battles of Frederick the Great and Napoleon. Instead of the sanguinary hand-to-hand fight with cold steel, we now have a prolonged fire fight carried on by a firing line which requires to be constantly fed by troops held in rear, who have to be sheltered as much as possible from hostile fire until the moment of their employment.
