Pennon in the context of "Heraldic flag"

Uhlan (/ˈuːlɑːn, ˈjuːlən/; French: uhlan; German: Ulan; Lithuanian: ulonas; Polish: ułan) is a type of light cavalry, primarily armed with a lance. The uhlans started as Lithuanian irregular cavalry, that were later also adopted by other countries during the 18th century, including Poland, France, Russia, Prussia, Saxony, and Austria. The term "lancer" was often used interchangeably with "uhlan"; the lancer regiments later formed for the British Army were directly inspired by the uhlans of other armies (even though they were never known by that name).

Uhlans traditionally wore a double-breasted short-tailed jacket with a coloured plastron panel at the front, a coloured sash, and a square-topped Polish lancer cap (rogatywka, also called czapka). This cap or cavalry helmet was derived from a traditional Polish cap design, formalised and stylised for military use. Their lances were traditionally topped with a small, swallow-tailed flag (pennon) just below the spearhead.

A knight banneret, sometimes known simply as banneret, was a medieval knight who led a company of troops during time of war under his own banner (which was square-shaped, in contrast to the tapering standard or the pennon flown by the lower-ranking knights) and was eligible to bear supporters in English heraldry. The military rank of a knight banneret was higher than a knight Bachelor (who fought under another's banner), but lower than an earl or duke.

Under English custom the rank of knight banneret could only be conferred by the sovereign on the field of battle. There were some technical exceptions to this; when his standard was on the field of battle he could be regarded as physically present though he was not. His proxy could be regarded as a sufficient substitution for his presence.
