In a "follow and assume" tactical mission, what is the role of the second committed force?

In a "follow and assume" tactical mission, the role of the second committed force is to ensure continuity of the mission, especially in circumstances where the lead force encounters insurmountable challenges or becomes incapacitated. This means if the lead force is unable to complete their objectives, whether due to a tactical withdrawal, heavy resistance, or sustaining casualties, the second force is prepared to take over and manage the mission.

This operational approach enhances resilience by creating a safety net that ensures the mission can still achieve its goals, even if the first force falters. It emphasizes the need for strategic planning and quick adaptability on the battlefield. The reinforcement aspect allows for a swift transition in leadership on the ground, maintaining pressure on the adversary and keeping the momentum of the original mission intact.
