If I was to write a screenplay for a contemporary Red Dawn film, then I would use a combination of a legitamate country or group of countries working together and radical organizations to be used in the suppression of an American town to be liberated from a group of teenage heroes who have no military training, military discipline, access to military weapons beyond any liberated arsenal, and be able to evade enemy forces with no supply network of lodging, food, clothing, medicine, intelligence information beyond any liberated ability while efficiently killing enemy forces, destroying enemy equipment, hindering any enemy expansion, and raising morale both behind enemy lines and in any Free America Zones.
With the catchphrase,
WOLVERINES!!!!!!!!!!!!!!!!!!!!!!!!!
