front lines

"Front lines" refer to the areas where opposing forces in a conflict directly engage each other. It is the zone of active combat, often marked by soldiers, tanks, or weapons facing off. Think of it as the battlefield’s boundary between different armies or sides, where most of the fighting and movement occurs. The front line can shift over time as battles progress, advance, or retreat. It’s a term that emphasizes the frontline’s dynamic role in warfare, representing the immediate contact point between opposing forces.
