'Platoons' in the Bible

This record of the warriors who were for David included Hachmoni's son Jashobeam, leader of the platoons, who killed 300 with his spear in a single encounter.

Joab's brother Abishai was the lieutenant in charge of the platoons. He used his spear to fight and kill 300 men, gaining a reputation distinct from the Three.

He was well known among the platoons, but he didn't measure up to the Three Warriors. David placed him in charge of his security detail.
