Does J troop exist in the US Army?

Answer 1

The real reason is because the regimental system predates the modern alphabet. Why would J and I be more confusing than I and L? that does not make sense. It took 200 years for the 17th century modern alphabet to catch on. Kind of like the metric system today. There is no letter J in the Old English alphabet, so the military never went back and added a J Troop. The architect manuals when Washington DC was developed were all in the Old English, so you have no J street.

Answer 2

Question: Does Company J exist in the US Army. Answer: The infantry division during WW2 contained 3 Infantry Regiments. Each Regiment consisted of 12 companies, identified A---through---M but it omitted Company J. There was no Company J. I assume this is still true today. A modern division consists of from two to four maneuver brigades. A Light Infantry Division during peacetime has two active-duty infantry brigades plus one US Army Reserve brigade. The 82nd and 101st Airborne Divisions carry three active-duty infantry brigades. In a heavy division, there are four maneuver brigades. If it is a Mechanized Infantry division, there are three brigades of infantry and one of armor; an Armor division has three brigades of armor and one of infantry. Each brigade consists of three battalions, each of which contains either three or four line companies (armor has three, infantry four) plus a headquarters company. Each battalion's line companies will be named A through D--you won't find an E company in a maneuver battalion. Now, as to the question...a "troop" is a company-size Cavalry unit. A modern division contains ONE squadron of cavalry, which contains A through D Troops.
