Hey, Jason. You may want to add Spectre Miniatures (
https://www.spectreminiatures.com/) to the 28mm list. They tend toward ultramodern rather than Cold War but that's not necessarily a bad thing. They also have one of the better selections of realistic (i.e., not "Kevlar bikini" styling) of armed female figures out there. No US distributor but I've not had problems ordering from them.
Hasslefree Miniatures (
https://www.hfminis.co.uk/) also has some stuff usable for T2k, though the selection is hit-or-miss and they're expensive. I've seen them in local stores, so someone is importing and distributing them in the US.
