Stupidest cliche scene in the movies is an unarmed helicopter chasing down some guy. The sad truth is, against an unarmed helicopter, a guy on the ground with a large rock or stick can easily take it down if it did chase him. Simply toss large rock or stick straight up into the rotor blades.

Now, against an ARMED helicopter, I imagine the archers are winning due to maintenance issues. Gunships are delicate things and sometimes they just fall out of the sky.
