Being a caravan guard was not a terribly challenging job. The one requirement was the ability to be walk as fast as the wagons, which lumbered along at a speed most five-year olds could match. Actual weapons proficiency was useful, but not required. Those merchants with valuable goods, or vengeful enemies, brought their own personal guards. You were responsible for the animals and the caravan staff, not the goods. So guard came down to playing sentry, lobbing things at curious wild animals, and finding new ways to pass the time while walking.
