Red Dawn II
Here's a scenario for you:
Armed forces of a foreign nation have landed on US soil, and a battalion of their infantry is marching toward your county seat, intending to depose the local government and take control. They will arrive in 12 hours; the US Army says a mixed division of infantry, air cavalry and armor will be there in 24 hours.
The invaders number about 2,500; they are carrying Chinese-made AK47s and grenades. They have a couple dozen RPGs. They are marching boldly down a four-lane highway through hilly country, partly farmland and partly wooded. A few miles outside town, the highway crosses a wide, swift-flowing river via a suspension bridge. When they get to your town, the first thing they'll see is residential subdivisions.
The county commissioners have asked you to organize the resistance. The call to action has been put out, and you find yourself in command of the following:
200 people with shotguns.
300 people with scoped, bolt-action hunting rifles.
200 people with lever-action rifles.
150 people with AR-15s, AKs, SKSes, and FN/FALs.
150 people with assorted handguns.
500 military veterans who want to help but are not armed.
One guy who runs a construction company, offering the use of his heavy equipment and the 4500 sticks of dynamite he has in stock.
Five private pilots with single-engine planes. Two are crop dusters.
20 people with boats moored along the river.
You have plenty of vehicles and gasoline, and all the stores in the area have offered as much ammo as you can use, and anything else you can think of. You have about one cell phone for every five people, and 200 FRS walkie-talkies with about a 2 mile range.
All 1500+ of your troops have gathered in the school gym to await your orders. What do you do? What orders do you give?
"As I looked at my two young sons, each with his gun, and considered how much the safety of the party depended on these little fellows, I felt grateful to you, dear husband, for having acquainted them in childhood with the use of firearms."
