Which of the following is NOT an advantage of a well-constructed individual fighting position?

A well-constructed individual fighting position is designed to provide several tactical advantages for a Marine in combat situations. One of the key characteristics of such positions is enhanced concealment, allowing personnel to remain hidden from enemy observation and fire, thereby increasing their survivability. Additionally, these positions improve security by providing a fortified area where Marines can defend against enemy attacks.

Furthermore, better defensive capabilities are a significant advantage; a good fighting position allows for cover and provides a fortified area where the defender can engage the enemy effectively, making it more challenging for the enemy to inflict casualties.

In contrast, increased mobility is typically not an advantage associated with individual fighting positions. These positions are meant to be stable and secure, often limiting rapid movement in the immediate area. While mobility may be crucial in different operational contexts, a well-constructed individual fighting position focuses on providing protection and a stable platform for defense rather than facilitating movement. Thus, the correct answer identifies increased mobility as not being an advantage of such positions.
