We're accustomed to games that reward experience based on kills or proximity to battle, but that is simply a limitation of computer-based games. In the old rpgs, you didn't gain a 'level' until you actually spent time training with an instructor, and you could gain the prerequisite 'experience' by doing almost anything related to your character.
To further point out "old rpgs" and leveling: A lot of RPG games discusss alternate methods of gaining exp. Like in D&D when a rouge scouting ahead of the group find a trp and disables it, or even if the group comes along and sets it off, disarming the trap gives exp, and even just surviving the trap is enough to garner some points. (After all, exp from combat is just a reward for surviving the battle). And some DMs give roleplaying xp.
That being said we only know for a fact units gain level by croaking enemy units and winning engagements (Bogroll leveling, twice, when he croaked Ansom, Stanley complaining that his warlords won't level when attakcing the siege if they run away from every fight).
