You dont see these troops ever. You do see the Gou’auld with the bog standard Jaffa always at their side, even as their personal entourage. If they had “shock troops” or star wars style “red guards” they would have shown them in the series.

Serpent guards are the elite of apophis. Other goa’uld have similar elite forces that guard the goa’uld. The First Prime is the foremost jaffa in the goa’uld’s personal guard.
