Swiss marksmanship

There is a story, possibly apocryphal, that a ranking German (possibly the Kaiser) was visiting and watching the Swiss military on their summer maneuvers.
He asked the Swiss commander, "How big a force do you command?"
The Swiss general confidently replied, "I can mobilize one million men in twenty-four hours."
The German asked, "What would happen if I marched five million men in here tomorrow?"
The Swiss replied, "Each of my men will fire five shots and go home."
