France
The modern French Army is composed of (foot soldiers including infantry and combat engineers) and (mounted soldiers such as armored cavalry units, and transportation units). Nowadays, the term (squadron) is used to describe a company () of mounted soldiers but, for a long time, a cavalry corresponded to an infantry battalion, both units grouping several companies (battalion and ''escadrons'' were tactical units while the companies were administrative units). The term has been discontinued and replaced by in cavalry units since 1815 and in transportation units since 1968.
In the "mounted arms" a
captain (three , or braids) in charge of an is thus called a (which is a title, not a rank). However, his superior in the hierarchy (four ) has the rank of (the equivalent rank in infantry units being ). After 1815 (in fact around 1826), the army began to write with an ''s'' in cavalry units to reflect the fact that this officer who used to be in charge of one squadron
[Prior to 1776, a two-company squadron was led by the most senior of its two captains. The single-company squadron of 1766 was led by a captain assisted by a "captain in second". Then, when the cavalry went back to two-company squadrons in 1788, the rank of "Chef d'escadron" was created but discontinued after a few years and, when reinstated, the chef d'escadron (without s) became a superior officer, typically in charge of two or more squadrons during the napoleonic wars while individual squadrons were again led by their senior captain. Then, when the company was abolished in 1815, squadrons were led (as in 1776) by a captain assisted by a second-captain while a chef d'escadron (without s) was in charge of several squadrons. A few years later (around 1826), the cavalry got into the habit of spelling chef d'escadrons with an s.] (several companies before 1815) was now in charge of several squadrons (i.e., companies). In other mounted branches (such as and ), is still spelled without ''s''.
Norway

The Norwegian army operates with units called ''eskadroner'' (pl.), typically a company-equivalent unit, generally in armoured cavalry units although not always.
The
2nd Battalion, Brigade Nord, has a company-equivalent unit called ''kavalerieskadronen'', or "the cavalry squadron". It serves as the main reconnaissance unit in the battalion. Like the mechanized infantry units, it wears the distinct khaki-coloured beret of the battalion instead of the normal black for cavalry units.
The
Armoured Battalion (''Panserbataljonen'') has the majority of its constituents labeled ''eskadroner''. Including the Cavalry Squadron, the Armoured Squadron and the Assault Squadrons. It also includes the battalion's Support element, the Combat Support Squadron. Its members are also referred to as dragoons, reflecting the nature of the unit.
The
Telemark Battalion also has a number of units labelled ''eskadroner''. This includes the Armoured Squadron, the Cavalry Squadron and the Combat Support Squadron.
Kampeskadronen
( Kampeskadronen) (roughly translated to "The Battle Squadron"), a Squadron consisting of two Mechanized Infantry Platoons, mounted on CV90's, one Armoured Platoon with Leopard 2's and a Combat Service Support Unit. Its soldiers were referred to as dragoons and consisted mostly of conscripted troops. Used as OPFOR in exercise operations with other parts of the Norwegian Army.
