The image link was very likely just a bunch of repainted hoplites with slightly different outfits; but then, thats the whole idea, to show their armor color and whatnot. There wouldn't be anything particularly astounding about a Sacred Band unit, I think, sword, spear, or mounted. I think a slightly modified and recolored Hoplite would do the trick. I'd add 'ancient cavalry' to that, but thats C3C materiel. The "spears" for the Sacred Band would be more along the lines of Sarissa, but since its hard to fit an 18 foot pike in a civ unit (or a wee little model), a little spear works better. The Sacred Band I know was a phalanx-style force that was routed in 341 BC, again in 311 (both of these in Sicily), and were reformed in 310, only to be defeated again (I think this was in Carthage). In their defense, they were supposedly the last unit to break. However, unlike almost the entirety of the more famous (and victorious) Carthaginian forces, they were actually of Punic descent, and not African or Spanish mercenaries. The force would have been 2 or 3 thousand men strong. AFAIK, they never used horses, although they probably had swords as a sidearm. For civ purposes, since its a game, it would make plenty of sense to make them into cavalry, swordsmen, or whatever, which is what most games (Read: Rome Total War) do, since "Sacred Band" sounds like a cool prefix to attach to a unit name.
