0.50 Caliber Venom dart takes out mines
This is a modified satelite-guided bomb which releases thousands of darts carrying the chemical DETA that's meant to take out mines. The Venom dart can go through ten to twelve feet of water or two feet of sand and still retain its effectiveness. Although I'm not entirely sure what the chemical is for. I'm guessing they're pheromones so that when the dart gets to the mine they'll wind up falling deeply in love with each other.
