Re tracked vehicles in Kiev. Thanks ORAC, makes more sense and fits the footage that I saw.
Incidentally I have seen footage of Russian armour entering from the Crimea with a diagonal white line along the vehicle sides; in other regions vehicle columns seem to be marked with a large O, a large triangle, a horizontal red line, or a Z, for starters. I think Putin may be wanting to show his force as some kind of quasi 'UN' peace keeping mission.
Rumour warning. One Japanese news site reported today that three bridges have been blown to the north and east of Kiev. Usual disclaimers apply.
