As I understand it the Byzant Janizars are a Vostroyan-looking regiment of Old Terran ground pounders.
The only Imperial Army coverage in Book 4 deals with the Solar Auxilia, that being the term given to deep space troopers of the Saturn Polities when they entered Imperial service, and those units raised subsequently following the same template.
Aye, much like Cadians are the standard template for the
IG in the 41st millenium, the Solar Auxilia are the standard template "elite" non-Marine force of the 31st. There are some brief references to some of the other Army units from the novel series, the Lucifer Blacks in particular if I recall correctly, but the wider Imperial Army will be coming at a later date.
