DF'85 WMD

[tbridges]

Playing my first game of DF'85 and I have a couple of questions. My WP opponent has just used his WMD for the first time.

If a hex has been struck with WMD, do the units that were the victim of the strike have to evacuate the hex on the next turn? If they remain in the hex, do they suffer the effects of the weapons again on the next turn (s) just by continuing to hold their position in that now contaminated hex?

Second question. Now that WMD have been used, my Command Report lists the number of WMD I have available. I'm wondering if this amount is the total available for the entire rest of the game (its a long scenario) or do more weapons become available as the game goes on?
