Lieutenant colonel

Lieutenant colonel was an infantry officer rank in many military organizations such as the Bajoran Militia, where it was known as field colonel and the Klingon Defense Forces. It was the second-highest officer rank, immediately below colonel. In the Starfleet Marine Corps, they can be referred to as a field officer. They act as either--but not limited to--the commanding officer of a battalion or executive officer of a regiment.
