What does 'reverse slope defense' refer to?

The term 'reverse slope defense' refers to a defensive strategy in which forces are positioned on the opposite slope of a hill from the enemy's perspective. This positioning provides several tactical advantages. By setting up defenses on the reverse slope, friendly forces can avoid direct enemy observation and fire, making them less vulnerable to incoming attacks. The terrain on the reverse slope can also provide natural cover and concealment, allowing troops to prepare their defenses effectively and coordinate counterattacks while denying the enemy a clear shot. This approach leverages elevation to enhance defensive capabilities while minimizing exposure. Consequently, it enables the defending forces to maintain a position of strength despite being out of sight from the enemy.
