[FASTBOAT TOUGH]

Storage or destroyed by treaty agreements. Besides the basic game issues of available slots for these types of units for the countries most likely to have them, the use of gas is considered just as bad as the use of nuclear weapons. Most countries to put things in prospective, have signed a multitude of treaties against the use of gas whereas the same can't be said about CM. The last major use of gas between warring countries I can think of was the Iraq and Iranian War which saw some world condemnation while they fought it out for around 8 or 10 years. And there is a more practical reason as well, it's a good way to kill your own forces as well since mother nature can play her cruel jokes on the user as well with wind and other forces of nature depending on the agents being used. You could argue about NBC protection but then why bother? Escalation is a another battlefield consideration you'd only be a step away from the use of tactical nukes. Bottom line for tactical use unlikely therefore it wouldn't fit this game I would think, on a strategic level possible but with severe consequences, it simply for here or real life be "game over".
