You know...one can in fact learn from observation. So you don't actually have to fight with a sword to learn how to use it. Of course, you'd suck at it, which is reflected even in the game: You gain swordfighting skill fairly slowly while leading I/MI/SF. As for getting wounded, well, sometimes an arrow does fly far and hit you, or the infantry line is broken and some dude manages to nick you. Or a piece of crumbling wall smashes you and you're not like that orc in LoTR: RotK who sidesteps at the last second. But don't worry, as long as you're not a hero you have contractual immortality in battle. The....uh...invisible deity of the battlefield is protecting you or something. Heroes throw away that protection by seeking immortality through death, the ancient Greek tradition. Either that, or their hubris in declaring themselves as heroes angers the Battle God and he/she/it revokes the contractual immortality.
