How is "close combat" defined?

Close combat is defined as engaging the enemy at short range involving direct confrontation. This definition encompasses various forms of face-to-face fighting, such as hand-to-hand combat or the use of small arms at close distances. In close combat situations, physical proximity to the enemy becomes a critical factor, as it often involves immediate tactical maneuvers and rapid decision-making.

This definition stands in contrast to other kinds of combat, such as ranged combat, where distance is a significant element, or strategic retreats, which are more about repositioning rather than direct confrontation. Aircraft ground support operations also do not fit under the close combat umbrella, as they typically involve engaging targets from a distance using aerial assets. Thus, option B accurately captures the essence of what constitutes close combat.
