Well, look up Lt. Reed and Star Trek Enterprise and he's British and looks quite a bit like these other guys to a certain degree. Now, I can't tell PanSlavs apart but I can tell the languages apart. As for Asians, I can tell a Japanese person from a Chinese person but getting specifics such as Korean or Vietnamese is much harder and I would only be able to geuss. Though I would have a fighting chance at geussing if their Philipinio because they sound russian but look asian thus they live in the philipines. I may be able to tell apart Vietnamese since I tried to date one (and failed ) but generall I can only point out if they're chinese or japanese 90% of the time. At a second and third glance I too think it says "firearms instructor".
