Now that you know about Order of Battle, and how Army units come together like a Matryoshka doll, it is time to learn about the personnel that constitute those units. There are two main subdivisions of military personnel – enlisted and officers. A third division, warrant officers, exists, but not all service branches have them, so they will be discussed as a footnote of sorts in Part 3.

Enlisted men used to be tradesmen. Your gunsmiths, tanners, welders, farmers, and wagon drivers served as foot soldiers and, perhaps eventually, sergeants, in the old days. The officers came from money or prestige, and since the dawn of military history, this class warfare has existed in which many officers who couldn’t shoot the broad side of a barn or lead a dog to a meat wagon held high rank, much to the chagrin of the enlisted ranks.

All enlisted soldiers are outranked by even the most junior of officers. This is a technicality of the Chain of Command and must be that way to preserve order and discipline, but no green Second Lieutenant would dare boss around a senior non-commissioned offer, whose boss is usually an officer high above that Lieutenant in the pecking order.
