"Remember guys, respect their inferior numbers to make it an even fight!"

10 guys should always beat one guy no matter how skilled the one guy is. The same goes for 4 guys.
3 guys will usually win against one guy. 2 guys have an advantage, but if one of them goes down first anything can happen.
Let there be strength in numbers. That is how the real world ususally works, unless you are a Spartan guarding a chasm.
