What is the length of TFOCA mils?

The length of TFOCA, which stands for Tactical Footprint of Combat Area, is important for understanding the effective range and capability of a weapon system. In the context of the question, the correct choice of 500 meters reflects the standard measurement used in military applications for TFOCA. This measurement helps in planning and execution during operations by establishing the area within which the weapon's effects can be reliably expected, ensuring that tactical decisions align with the operational range of the missile systems involved. Clarifying the impact of TFOCA helps personnel to better plan for placement, engagement, and follow-up actions in the field.
