In all of their colonies the French recruit regular units from local native troops. Venus is no exception, where the Tirailleurs Cytheriens have been formed from allied parrotmen:

Of slightly shorter stature than the 'wild' parrotmen, the parrotmen recriuited for the tirrailleurs are chosen from 'civilised' races that do not display the unpredictability of the 'wild' parrotmen. They tend to be slightly smaller than their wild cousins, but make up for this in their ability to take on military discipline. Their firepower tends to be better than that of their wild cousins, due to a combination of superior ammunition manufactured by the French and their European military training, including volley fire.
