Which of the following is not a mission task of the CAB?

The correct choice indicates that Ground Reconnaissance is not considered a mission task of the Combat Aviation Brigade (CAB). The CAB primarily focuses on aviation-related operations that support the maneuver elements of the Army.

Movement to Contact, Air Assault, and Aeromedical Evacuation are all core tasks that fall under the CAB's responsibilities. Movement to Contact involves the rapid deployment of aviation units to close with and defeat the enemy. Air Assault refers to the operation where forces are inserted into an objective area by rotary-wing aircraft to accomplish a specific mission. Aeromedical Evacuation pertains to the transport of injured personnel from the battlefield to medical facilities using aircraft, ensuring timely medical care.

In contrast, Ground Reconnaissance is generally conducted by ground forces to gather intelligence about enemy positions and activities. While aviation units may assist or support reconnaissance through aerial surveillance, conducting ground reconnaissance itself is outside the primary mission scope of the CAB. Thus, identifying Ground Reconnaissance as not being a mission task of the CAB aligns with the definition of the brigade's operational focus.
