Falling Skies, American Standards

We've been watching Falling Skies which is a passable sci-fi TV series. After 3 episodes I can safely say passable largely because we have to avoid X Factor & Come Dancing somehow. Early on the lead gives an example of smaller forces defeating larger forces : the Athenians at Marathon, ok. The Scots against the British. Yes, I can now confirm for any American readers that England is just a few miles South of London.
