Mix-ups are also common with unit types. As with previous Empire Earth games, units are often jumbled together from various eras. Here, however, this tendency seems even more pronounced due to the use of just five eras (ancient, medieval, colonial, modern, and future). It's common to find all sorts of bizarre units marching side by side. So if your sensibilities are offended by troops wielding Gatling guns and arquebuses on the same battlefields, give Empire Earth III a pass. If this isn't enough to turn off armchair historians, numerous goofy units with no basis in reality should certainly do the trick. The Middle Easterners are probably the biggest offenders here, with camels that can lay a hurting on enemies due to a special stench attack and a hero prophet unit that can call forth a plague of frogs. While there is a place for such units in an RTS, they don't fit in a game seemingly designed to be a more serious, more authentic take on conquering the globe.
