Brigadier
Brigadier was the most junior military flag officer rank, the equivalent of which was used by the service organizations of many civilizations. As a traditional grade, brigadier, also known as brigadier general, was, by definition, the officer in charge of a brigade. In comparison to naval ranking systems, it was equivalent to the rank of commodore (or rear admiral lower half).

In an alternate 1944 -era on Earth, the German Army brigadier general, know in by the German equivalent generalmajor, reported directly to Adolf Hitler from the American White House. ()

On the planet Ekos, there were the equivalent ranks, based on the original Earth ranks, carried by the Ekosian Nazis during the 2260s; the aforementioned Heer generalmajor, the SS-brigadeführer (brigade leader), and the Nazi Party rank hauptdienstleiter (head service leader). ()

During the 23rd century, brigadier was a rank in the Klingon Defense Force, and was someone who served as a military adviser to the Klingon chancellor, and had the authority to speak on behalf of the Klingon Empire. ()

Background information 
According to the , brigadier general was a rank in the Military Assault Command Operations in the 2150s. The insignia for this rank was on display in a diagram of MACO rank and insignia.

For the episode "Patterns of Force", costuming for the Ekosian SS seemingly used the entire spectrum of Nazi rank insignia available, overlapping several variations of any one insignia's evolution. A prime example of this was the appearance of the SS brigadeführer's collar badge, as in the real world, the badge in question – two oak leaves and a pip – was replaced after April 1942 with three oak leaves.
