The main difference between "après" and "après que" is that "après" is a preposition that means "after," while "après que" is a conjunction that means "after" or "after that." "Après" is used to indicate a time relationship between two events or actions, while "après que" is used to introduce a subordinate clause that expresses an action that occurs after another action. For example, "Je suis rentré après le dîner" means "I came back after dinner," while "Je suis rentré après que le dîner était fini" means "I came back after dinner was finished." **

Ultimately, the specific skills and training required for mountain troops will depend on the specific needs and conditions of their operational environment. **
