Field-grade and company-grade officers were distinguished by the fringe on their epaulettes. The ranks for officers shown on that diagram are anachronistic; during the Napoleonic era, Hauptmann was known as Capitaine or Kapitän, Oberleutnant was Premier-Lieutenant, and the lower Leutnant was Seconde-Lieutenant. There also existed below captain the rank of Stabs-Kapitän, which was originally a title denoting the commander of a company which had a field-grade officer or general as its nominal chief. This became superfluous after the reforms of 1807 when all companies ideally had a full captain.
Before 1807, the company's colours were carried by a Gefreiter-Corporal or Junker, a nobleman and officer-candidate serving as an NCO for a period of time. Of the ten junkers in a regiment (grenadier companies having none), the five oldest held patents for the rank of Fähnrich (Ensign) or Kornett in the cavalry and were styled "Portepee-Fähnrich" and was permitted to carry an officer's sword and sword-knot. After the reforms, Gefreiter-Corporal and Fähnrich/Kornett were abolished and the colours were entrusted to an experienced NCO of any rank or social class, who apparently was then known as the Portepee-Fähnrich.
In this table of personnel and salaries for the 7th Reserve Infantry Regiment
from 1813, a 3-battalion regiment of 12 companies had in each company:
1 Feldwebel (Sgt. Major),
1 Kapitain d'armes (NCO in charge of company weapons and equipment)
1 Fourier (a quartermaster in charge of establishing camp and caring for rations/forage)
1 Portepeefähnrich (the company colourbearer)
and 10 Korporale
A Gefreiter was not an NCO, but a senior private entrusted with certain duties like commanding a guard detachment, and would be among the first men to be considered when a vacancy in the corporalcies opened up. They were not distinguished in dress from regular Gemeine.http://www.napoleon-online.de/pr_1806infanterieOffiziere.htmlhttp://www.napoleon-online.de/pr_1806infanterieUffz.htmlhttp://gdz.sub.uni-goettingen.de/dms/load/img/?PID=PPN682442984
