In operational terms, how is 'lateral movement' defined?

Lateral movement is defined as shifting units horizontally along the front without changing direction. This tactic is essential in a military context because it allows a unit to adjust its position on the battlefield to respond to changes in enemy positioning or to occupy more advantageous terrain while maintaining the same overall direction of advance or defense. By moving laterally, forces can effectively present a different front to the enemy, address threats without compromising their formation or momentum, and facilitate coordination with adjacent units. This tactical flexibility is crucial for maintaining operational tempo and seizing the initiative in combat situations.
