Final answer:
The correct answer is option a) Counterforce weapons need to be more accurate to target military installations.
Step-by-step explanation:
The question compares the need for accuracy between two types of strategic weapons: counterforce and countercity weapons. A counterforce weapon is designed to target the enemy's military capabilities, such as missile silos, command centers, and other strategic military targets.
Since these targets are often specific and may be located away from civilian areas, greater precision is required to ensure they are effectively neutralized without causing unintended damage to nearby non-military areas. Thus, the correct answer is a) Counterforce weapons need to be more accurate to target military installations.
Conversely, countercity weapons are intended for broader targets, generally aiming to disrupt or destroy infrastructure and population centers. While minimizing civilian casualties is always a consideration in warfare, the nature of countercity weapons implies a less precise targeting approach compared to counterforce weapons, given their strategic objectives.
