12 GA Perimeter Alarm

There are all sorts of "choke points" that will restrict an opponent to just one coverable approach - bridges are not the only one. The thing is, you have to guess, and guess correctly, what sort of opposition you plan to face. For example, bridges and ground choke points and funnels would work against zombie hordes and the average looter gang, but they don't have choppers and drones, as a rule. For those, you need other defenses, the best of which is just not to allow them to see or target you.

Also, remember that if you have a really good choke point that restricts THEM to one approach, it also restricts YOU to that same approach - or exit. You have to plan accordingly for that. Most sieges fail for the defenders in the end for lack of proper supplies, or properly hidden exits in case withstanding a siege becomes untenable. Vercingetorix withstood the might of the Roman Army under Julius Caesar, for years by avoiding sieges, and destroying his own countryside in a scorched earth campaign to deny supplies to the enemy. It didn't fail until the siege of Alesia, when he stopped running and forted up.

Vercingetorix in Gaul and Spartacus in the home turf of Italy both ran running campaigns (as did Eric Rudolph and Lewis Redmond here in the Appalachians against Federals), and allowing themselves to be besieged was their downfall in both cases. The last stand locations of both had good covered exits, but they both just exfiltrated to weakest people to safety, and met their end on their own terms.

We know the end of Vercingetorix - five years after his capture, he was paraded through the streets of Rome and beheaded in a "victory celebration" by Caesar. the end of Spartacus is only assumed, as his body was never identified among the dead. Most assume that he was buried in secret by his escaping followers, but I like to think he lived and made it back to his homeland of Thrace, and died of old age there. There really isn't any evidence at all for which way it really went. The Romans had a vested interest in spreading the rumor to both citizen and slave that he was killed for his impertinence - I suspect that account, because of it's source and the political expediency involved... especially since they utterly failed to produce a body, or even just a head. I think he outwitted and outmaneuvered the Romans in the end and made it out alive. What he would have thought of that outcome is anyone's guess.

In the end, it's always best in my mind to keep 'em guessing, and looking over their shoulders forever - long past your actual expiration date.

We can all dream, can't we?
