Organized marauders, a serious thorn in the back of regular armies

This sort of static defence would be almost useless against a modern army, but against lightly armed marauders (who would probably be unwilling to take serious losses) it might work.

To be honest, by the time folks are using this kind of system, organised, modern armies will cease to exist.

Nobody would be willing to take excessive casualties so it would work against not just marauders but enemy forces aswell.
