Definitely a longer-term project, though. Between the guns, the LBE and the uniforms it's going to cost. On the plus side, Russian military doctrine does not classify pistols as combat weapons (or they didn't until very recently). That means we don't have to worry about sidearms. But yes, I think a Russian-themed outfit is very doable, and if we trained properly it'd be effective as all hell. Russian isn't that widely known, either, so using it over comms would be great OPSEC.
Even better if we could find some genuine Russians to advise us on details or even play with us.
