Training is only part of the equation, drilling is just as important. For a full time soldier training does not end once one is fully inducted into the unit, they practice constantly to stay in top order and to maintain cohesion. One can be a great warrior who is excellent in a fight and skilled with weapons but a piss poor soldier who does not follow orders and does not work as part of a team. The Qing bannerman class in the Qing Dynasty was a hereditary military class in which every able bodied man was required to train and serve as a soldier, but as drill requirements were both low and laxly enforced at best. The result was an inferior army even factoring in it's other deficiencies.



Full time warriors is a category which includes but is not exclusively composed of members of hereditary warrior castes like knights or samurai. Though it's a lot less romantic a solid and well supported standing army composed or rigorously trained soldiers recruited from the common folk can match such a warrior caste. Even so a standing army is not necessarily up to said snuff. Conscripts in the Russian Imperial Army would be more akin to the feudal levies and there would be intermediary units.
