How many combat positions are typically used in a defensive strategy?

In a defensive strategy, three combat positions are typically used to establish a layered approach to defense. These positions include the primary, secondary, and reserve positions.

The primary position is where the main defense is set up to confront the enemy's initial assault directly. The secondary position serves as a fallback point if the primary line is breached, allowing forces to regroup and continue to defend effectively. Lastly, the reserve position is held in readiness to support either the primary or secondary positions as required, providing flexibility and reinforcements as the situation develops.

This three-tiered structure enhances the overall defensive capability, allowing defenders to absorb and respond to enemy attacks more effectively while maintaining the initiative to counter with organized counterattacks when possible.
