The goose step is a special marching step performed on formal military parades and other ceremonies. While marching in parade formation, troops swing their legs in unison off the ground while keeping each leg straight and unbent.
The step originated in Prussian military drill in the mid-18th century and was called the Stechschritt (literally, "piercing step") or Stechmarsch. German and Soviet military advisors spread the tradition throughout the world in the 19th and 20th centuries. The goose step is now used by the militaries of over seventy countries, comprising three-fifths of the world's population.
The term "goose step" originally referred to a British military drill in which one leg at a time was swung back and forth without bending the knee. Apparently, standing on only one leg reminded soldiers of how geese often stand. The term was later applied to the German stechschritt during World War I. As a result, term has acquired a pejorative meaning in some English-speaking countries.
The goose step is a difficult marching style that takes much practice and coordination. It is therefore reserved for ceremonial occasions.
Goose stepping is often seen in military parades. Because it is difficult to maintain for long periods of time, troops only begin to goose-step when they approach the reviewing stand and return to a normal march step once they have marched past. Large military parades require several days of practice to ensure that troops can perform the goose step without injuring themselves. Preparatory training includes having soldiers march in small groups, with arms linked to maintain balance.
Honour guards also use the goose step during solemn ceremonies such as at war memorials or military cemeteries. The goose step has been featured in several Olympic opening ceremonies, as the host nation pays the same respect to the Olympic flag as to its own flag.
In the most rigorous form of the goose step, often found in guard mounting ceremonies, the pace is done at a slow march, and the leg is nearly horizontal, and sometimes well beyond. In a standard goose step, found in large military parades, the pace is done at a quick march and the leg is raised only to knee-height, or even to calf height. The lower goose step improves balance and unit cohesion at the tempo of a quick march. Flagbearers and honour guards will frequently march with a higher goose step than the mass of troops following.
