Who is the Battalion Commander?

The Battalion Commander is typically a position held by a Lieutenant Colonel (LTC). In a battalion, the commander oversees all operations, personnel, and resources, ensuring that the unit is ready and capable of completing its missions. This role includes significant responsibilities such as tactical planning, training management, and maintaining discipline and welfare among soldiers.

In this scenario, LTC Nielsen is identified as the Battalion Commander, aligning with the standard military hierarchy and the typical ranks associated with command positions. Other ranks in the options, such as Command Sergeant Major (CSM) and Major (MAJ), serve important roles but do not hold the command authority of a battalion, which reinforces LTC Nielsen's designation as the correct answer.
