Final answer:
Final protective fires are preplanned artillery fire support measures conducted at a distance range of a few hundred to a thousand meters from friendly positions.
Step-by-step explanation:
Final protective fires in military tactics refer to a preplanned artillery fire support measure to protect friendly forces from an enemy attack. These fires are usually conducted from a specified distance from the friendly positions. The question asks for the typical distance range within which final protective fires are conducted.
While the question does not provide specific numbers, it is important to note that the actual distance can vary depending on the tactical situation and the specific mission. However, as a general guideline, final protective fires are usually conducted within a few hundred to a thousand meters of friendly positions. This range allows the artillery to suppress or destroy enemy forces before they reach the friendly positions.
