What does the term "double-time" refer to in a marching context?

In a marching context, "double-time" refers to marching at an accelerated speed. This term typically means moving at a pace that is double the standard marching speed, which requires a quicker tempo and often involves a more vigorous movement of the legs. Double-time is used in military settings to increase mobility and urgency, enabling troops to cover ground more quickly compared to regular marching speed. Unlike walking casually or moving at a slower pace, double-time emphasizes both speed and the maintenance of formation, making it a crucial skill in various military operations.
