Which liaisons coordinate and synchronize SOF targets during planning?

The correct answer is C, SOLE (Special Operations Liaison Element). The SOLE plays a vital role in coordinating and synchronizing Special Operations Forces (SOF) targets during the planning phase. Its primary function is to serve as the liaison between SOF and conventional forces, as well as other elements involved in the operational process. By facilitating communication, the SOLE ensures that operations align with strategic objectives and that the specific requirements of SOF are integrated into the broader operational plan.

In this context, the other options may represent important components of military operations but do not focus specifically on the orchestration of SOF targets. The AOC (Air Operations Center) generally manages air operations and may coordinate with various units but is not specific to SOF. The BCD (Battlefield Coordination Detachment) works to integrate army forces into joint operations. The ISRD (Intelligence, Surveillance, and Reconnaissance Division) focuses on intelligence processing and analysis but does not primarily coordinate SOF targeting. Therefore, the SOLE stands out as the designated entity to synchronize SOF targets during planning effectively.
