High Colonel

High Colonel was a rank in the Imperial Army, usually having command of a Battlegroup.

A typical High Colonel had four regiments under his command, totaling just over ten thousand front-line troops, with the next highest rank being Brigadier. Such a command represented a significant military resource usually deployed for extended campaigns against organized enemies, although Imperial Army strategists did not consider it enough to undertake the conquest or pacification of an entire planet.

Its equivalent in the Imperial Navy was Captain of the Line.
