Wiki is a great source-- I've had most of my elite units named after regiments of the British Army, or the Canadian Army (can't beat either for colorful names) or units in the US Army. I know there's no comparison, but I see an "army" as more or less a division, so they'll have corresponding names like "1st Armored Division" or "2nd 'Indianhead' Division" and so on.
