Time for a history lesson, provided from my good friend wikipedia
Stormtroopers (in German Sturmtruppen; the term "thrust troops", Stoßtruppen was also used) were specialist soldiers of the German Army in World War I. In the last years of the war, Stoßtruppen were trained to fight with "infiltration tactics", part of the Germans' new method of attack on enemy trenches. Men trained in these methods were known in Germany as Sturmmann (literally "storm man" but usually translated as "stormtrooper"), formed into companies of Sturmtruppen ("assault troops", more often and less exactly "storm troops"). The infiltration tactics of the stormtroopers are still in use today, in one form or another. Other armies have also used the term "assault troops", "shock troops" or fireteams for specialist soldiers who perform the infiltration tasks of stormtroopers.
Tactics:
A short artillery bombardment, featuring heavy shells mixed with numerous poison gas projectiles, to neutralize the enemy front lines, and not try to destroy them.
Under a creeping barrage, Stoßtruppen would then move forward, in dispersed order. They would avoid combat whenever possible, infiltrate the Allied defenses at previously identified weak points, and destroy or capture enemy headquarters and artillery strongpoints.
Next, infantry battalions with extra light machine guns, mortars and flamethrowers, would attack on narrow fronts against any Allied strongpoints the shock troops missed. Mortars and field guns would be in place to fire as needed to accelerate the breakthrough.
In the last stage of the assault, regular infantry would mop up any remaining Allied resistance.
