After spending a few years in the colonial army, returning to Spain's native land will surely lead to a promotion. For those who have no background and rely solely on their efforts to rise, this is undoubtedly a great opportunity.
Moreover, compared to Spain's homeland, its colonies are more likely to face warfare. Even if it's merely a small-scale war against indigenous uprisings, as long as they win, the credit will be theirs.
As long as there is credit, whether it's a promotion in rank or the acquisition of land and titles, it is very promising, which is why Carlo is not at all worried about those military academy graduates opposing it.
The conditions in the colonies are, of course, tough, but it also depends on whom you ask. For the Spaniards, the biggest drawback of the colonies is the lack of medical facilities, which isn't much better in mainland Spain either.
