Ethnic cleansing in Geogia

According to the Sky news guy talking on Fox News, Russian militiamen are doing the dirty work of ethnic cleansing and presumably committing atrocities. I was amused that Russian APC's are described as "tanks". Fox News showed a column of really low-profile Russian APC's with a variety of turrets. Some seem to be armed with what was traditionally a smoothbore 3in gun and others had light automatic guns.
