Here's a breakdown of how armies are typically structured:
* Vanguard: The leading units that are responsible for scouting, screening, and engaging the enemy first. They are often lighter and more mobile than the main force.
* Main Body: The core of the army, containing the heaviest units like infantry and artillery.
* Rearguard: The units that protect the rear of the army and cover the retreat if necessary.
The vanguard plays a crucial role in an advance, as they set the tempo and determine the course of the battle.
