What is the rank of a Troop commander?

The rank of a Troop commander in Naval Special Warfare, particularly during the era of WWII and in the context of UDTs (Underwater Demolition Teams) and SEALs, is typically a Lieutenant Commander (LCDR). This rank is significant as it reflects the leadership responsibilities and authority expected of a Troop commander. In operations, a Troop commander oversees the planning and execution of missions, making critical decisions that affect the entire unit's success.

Historically, Lieutenants and Captains may hold varying responsibilities within a naval organization, but the role of leading a Troop, especially one involved in special operations, is usually reserved for a Lieutenant Commander level. Thus, within the structure of naval special operations during WWII, an LCDR would be the appropriate rank for someone in such a command position, balancing operational leadership with experience.
