Original: The tactics became especially associated with the stormtroopers of the German Army, where they were also called Hutier tactics, after General Oskar von Hutier, who used these tactics to great effect during Operation Michael in March 1918.
Simplified: These tactics were to prove so successful in 1917 and 1918 that the French dubbed them "Hutier tactics", although the more commonly used term today is "infiltration tactics".
