I'd never heard of these ladies before but apparently this is a persistent urban legend circulating through the Russian armed forces since the late '80s. I saw a reference to these "white tights" in a pulp mythology book while browsing at the book store. A google search turned this up:

Anyone heard about these chickss before?
Could make for an interesting T2K encounter/NPC/or femme munchkin PC. Normal PCs could use this myth to their advantage. I dunno. Just thought I'd post it here and see what else comes up.
