Hi Shane,
Give Andrew at Historica books a shout, he has Battalion figures, their modern Russian figures are superb. They also have a GRU officer in Afghan setting, fantastic figure. Russian kit and uniform has changed very little and even very modern figures can be made to easily look right in an Afghan setting.
Here's some links to figures on Andrew's site, great guy by the way:
