Exactly, I like to name my units once I get to the industrial/modern era, and send them out to conquer all those around. It makes it easier to look for units that are not just the generic name. I tend sometimes though, to name them after cities, like KMS Berlin and so on, rather than actual warships. I use U-1 for submarines for Germans and NU-1 for Nuclear Submarines. I wish though this isn't the correct thread that the infantry would merge with the paratrooper at Advanced Flight for the Civ4 and continue upgrading with mechanized infantry being a supporting technology, rather than the be-all and end all. Modern infantry do not only fight in vehicles.
