(mil.) The position of an army in the form of steps, or with one division more advanced than another. The word echelon is used also in reference to nautical manceuvres. When a fleet is in echelon it presents a wedge-form to the enemy, so that the bow-guns and broadsides of the several ships can mutually defend each other.
