Captain: Commander-In-Chief of an Army

When the officers have finished addressing the army, they are to appoint commanders to lead it.

So the LORD sold them into the hand of Jabin king of Canaan, who reigned in Hazor. The commander of his forces was Sisera, who lived in Harosheth-hagoyim.

His wife’s name was Ahinoam daughter of Ahimaaz. The name of the commander of his army was Abner, the son of Saul’s uncle Ner.

And the king appointed Benaiah son of Jehoiada in Joab’s place over the army, and he appointed Zadok the priest in Abiathar’s place.

…and the people in the camp heard that Zimri had conspired against the king and struck him down. So there in the camp that very day, all Israel proclaimed Omri, the commander of the army, king over Israel.

Ahithophel was succeeded by Jehoiada son of Benaiah, then by Abiathar. Joab was the commander of the king’s army.
