What about stink bombs (sulfer) or hot steam pumped through the caves?

Now that's a real intellectual solution. "Stink bombs and blowing steam?"

Four SAS guys have several holes in their bodies, and you think *war* is a big friggin joke.

Sulfur dioxide (one of the stinky parts of a common stink bomb) or several other organic sulfur compounds in even moderate concentrations and carried by steam could kill anyone inhaling it in a closed area.
