Robert's expeditionary force, it was truly vast.
He wished to recruit a significant number of soldiers for training, these people needed to be sourced from Holy Terra and from the nearest Nest Capital World—Necromund.
However, drawing such a large population away from construction would significantly undermine the economic development and investment of the Alliance.
To build more Starfighter Battle Groups, a considerable amount of population is needed for recruitment and selection as well.
The genetic seed stocks on Holy Terra and Mars would need to be utilized. The Original Casting technology developed by the Great Sage Kao'er would play a role; if there weren't enough genetic seeds, they could even directly extract genetic fragments from Robert and re-cultivate them—although this was rarely done.
In short, the genetic seeds weren't particularly a big issue.
But the issue was the population, and the money.
