An assault battalion was a formation of the Imperial Army.
Commanded by a Major, an assault battalion was comprised of a single line company, 2 assault companies, and a repulsorlift company, with the attendant battalion headquarters and support personnel. One assault company was always fully equipped, with the average battalion numbering around 868 personnel, 628 of which were combat personnel supported by thirty-one repulsorcraft. Assault battalions were often employed in urban environments, and were commonly employed as vanguard units for large-scale operations. Assault battalions were given priority over line battalions when it came to fire-support requests, and the battalion was occasionally reorganized so that the fully equipped assault company were carried by elements of the repulsorlift company. 
The Compforce Assault arm also maintained several assault battalions, which was organized into COMPNOR regiments. The main difference between the standard assault battalion and it's COMPNOR counterpart, was the lower quality of troops. And the lack of a security platoon. This was because COMPNOR personnel believed then self to be too unquestionably loyal, to ever require such a unit. Their motivation to serve the Emperor was also noted for been generally higher then the standard imperial army trooper and imperial stormtrooper.
