Sarah had just climbed a tree, with excellent view over the area, of course there was still the issue with the trees, but that couldn't be helped. She'd covered the ground with various traps. Trip wires, almost unnoticeable for the untrained eye. Noose traps, definitely more visible, but not if your running in fear. Land mines... Nothing fatal, mostly just light and a loud boom, but it was enough to keep them distracted. Then of course she placed out, some live explosives, to cause some visible damage, just in case the girls would figure out the mines were harmless. And when all else fails, Sniper rifle! Nothing like a rain of bullets to strike fear into the heart of man.
