Final answer:
Operational reach is the capability of a military force to project power across a distance and for a duration. The three elements that comprise it are momentum, logistics, and sustainability, all critical for military success.
Step-by-step explanation:
Operational reach refers to the distance and duration across which a joint force can successfully employ military capabilities. The three elements that comprise operational reach include the force's ability to maintain momentum, the extent of its logistical support, and its capacity to sustain operations over time. Understanding these elements is critical for successful military planning and execution.
Momentum - This element refers to the force's ability to maintain the tempo of operations necessary to achieve its objectives. Momentum can be affected by enemy resistance, terrain, weather, and the force's overall readiness.
Logistics - Logistical support involves the planning and execution of movement and sustainment operations to provide the necessary personnel, equipment, and supplies. A force's logistical capacity will dictate its reach and how long it can operate effectively.
Sustainability - Sustainability is the force's ability to maintain operations for the duration required to meet strategic goals. This takes into account the availability of resources, the resilience of forces, and the overall strategic context.
