"Would fuel-air explosives work well in a cave system? "

As I understand it, any underground facilities need to have an opening large enough for the air to suddenly rush out for fuel-air explosives to be effective (but I'm no expert). We've been aware of these caves for more than then years. (Hell, I've been aware of them for about 10 years) I'm only guessing, but there are probably counter measures prepared for sealing them in, probably involving seismic devises to map them and locate openings. If we can control the terrain for an extended period of time, we don't have to go in like the Vietnam tunnel rats.

Since those rats like Chemical weapons I say we seal the cave`s openings, then drill down into them and pump them FULL of nerve gas. Remember Vasques from Aliens, "we have seven canisters of CN20, I say we roll them in and nerve gas the whole F---ing nest!"
