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." **

While skiing skills are often associated with mountain troops due to the terrain they operate in, it is not a requirement for all mountain troops. Mountain troops can still exist and be effective in rugged, high-altitude environments without skiing skills. They may utilize other methods of mobility such as snowshoeing, climbing, or hiking to navigate the challenging terrain. Ultimately, the specific skills and training required for mountain troops will depend on the specific needs and conditions of their operational environment. **
