Which characteristic is important for a rally point?

A rally point is a designated location where a unit can regroup, reorganize, and receive further instructions or resupply during a mission. The essential characteristic of a rally point is that it should provide cover and concealment. This is critical for maintaining the safety and security of the personnel as they gather in one place, minimizing the risk of detection by the enemy.

Cover refers to physical protection from enemy fire, while concealment involves hiding the unit from enemy observation. A rally point that offers both allows the team to regroup effectively without exposing themselves to potential threats. It also allows for planning, rest, or re-supplying without the constant fear of being attacked.

Given this understanding, having a rally point that lacks these protective features could jeopardize the safety of the unit and undermine mission success. The other characteristics mentioned in the options do not provide the same level of operational security or utility in the context of a rally point's primary purpose.
