That one made me laugh out loud, but seriously, an entire army cannot simply turn tail and run, it would cause a serious traffic jam to say the least-even an unplanned turn-and-run retreat is a hard military manuever to complete, so to pull off such a manuever with thousands of fully armed Uruk-Hai in any kind of military order would be difficult. In all seriousness, if you to fight, how would you combat such a charge?
