Great point TDC, I had not considered the interesting historic parallels such a program would draw from the Ronin v. Gunslinger conflicts of the Star League era. I don't want to get sidetracked on a conversation on the Ghost Regiments or a Marine unit which I am thinking about too.
The idea for a Draconis Warrior Born Program would not start until 3051 at the earliest and has several hurdles to overcome. They certainly don't have access to Clan Breeding Tech (aka the Iron Wombs) or their Refined Genetic Materials (over 200 hundred years or 10 plus generations). You need set up time and it is going to be 16+ years (3067+) before the first 'Dragonborn' would enter service.
So the first generation of this unit would be select recruits and volunteers.
Agreed that the unit would have to be part of the Department of War like the Sword of Light, not sure what their exact relationship would be to the DCMS. Would a Warlord have any control over them? Likely if posted to their Military District, perhaps this gives the Galedon Warlord a special unit he can call upon and he actually approves? But yes there has to be some nefarious DCMS and ISF oversight present here perhaps making those two rival organizations allies in this respect.
I am not an expert on Japanese translations but what would you think of Mechasenshi? It takes 'Mecha' which was originally a Japanese abbreviation and adds 'senshi' which means warrior.
Over on OBT Ice Hellion pointed out that O5P is the center for martial arts training in the Draconis Combine. So why not have MechWarrior as just another martial art?
To that end he suggested applying the Dan system to their ranks which I did along with some other Japanese terms.

Also as a side note I am researching Yorinaga Kurita more who was exiled to a zen monastery on Echo V. The Kurita dueling system is very interesting as well. Reading up on the battles between Kurita and Kell there are several 'honors' observed which could serve as the core for a codified zellbrigen for these Draconian warriors.
