^ What's your choice? Between Draco (Is he the origin of the word 'Dragon' that means mythical firebreathing reptiles that some can fly), Cleisthenes, and Solon ?
UU Choice. if Trireme is to be generic naval unit of Classical Era.
"Dragon" in (archaic) Greek (δράκων) means 'sharp-sighted', so there is no relation to any flying beast. Draco (sometimes transliterated Drakon or Drako) may, therefvore, have been a Title rather than a proper name. For this argument is the fact that there is no patronym associated with his name ("Draco, son of X") in any text, nor is there any biographical information about him except a much, much later tale that he died in exile in Aegina. Against this is that as early as Aristotle he is referred to as a singular human being, not a mythical character, but until some new fragment of information surfaces, the archeological/historical Jury is still Out.
What is interesting is that aside from producing the first written Law Code for Athens (previous 'laws' were strictly oral and subject to interpretation in every case) he also set up the Council of 400, a decision-making body drawn from all the citizens who could afford a Hoplite panoply (shield, cuirass, helmet, spear). Therefore, although he may have merely codified and put in writing an existing social contract, the Hoplite System of self-armed militia Heavy Infantry can be attributed to him - meaning the Hoplite as UU could be a Leader Unique to Draco, if we want to go that way (I don't think we should: the Hoplite phalanx was too universal among the Greek city states to narrow it down to any single leader or city)
Much as I love the sheer variety and uniqueness of the Mediterranean polyremes, from Bireme to Decareme, they are Unique to the Mediterranean and peculiar to that sea, and primarily the eastern half of that sea plus Carthage. If we were being Realistic (Aaaaargh, he said That Word!!!) they would be disastrously fragile if committed to the North Atlantic or Indian Oceans: one of the first things the Romans commented on about the Venetii, the sea-going Gauls of the Frisian coast, was that their coastal galleys were built completely differently from the ships/boats the Romans were used to, with a strong keel and ribs and overlapping ("clinker-built" to use the later term) hull planking, and therefore far more sea-worthy in the North Sea and Channel coasts than any Mediterranean vessel of the time.
For military Uniques, there are plenty of Greek originals or adaptations to choose from:
1. Hoplite heavy spearmen
2. Peltasts, lighter and with more flexibility in rough terrain
3. The Katapelta, or "Shield-Piercer", the torsion catapult invented in Syracuse which spawned a whole variety of bolt and stone-throwers, siege and naval 'heavy weapons'
4. Phillip and Alexander's Pezhetairoi, phalanx of pikemen
5. Same duo's Hetairoi, or Companion Cavalry of heavy lancers
Of this short list, Pezhetairoi and/or Hetairoi could be Leader Unique(s) for Phillip or Alexander or a Macedonian Civ. The other three could be more general to almost any of the Greek city states or Leagues, especially the Peltast for groups like the Aetolian or Arcadian Leagues, both of which were based in rougher country than the Athenian Attic plains.
BUT for all the potential for variety, you have to come back in the end to the fact that Classical Greece is associated with the Hoplite as a Unique military system and unit.
