There was a topic discussing it in Moorcock's Miscelany but i cannot find it. There were also army lists for OOT, but neither i can find them. Anyway, if you look at this link:

"Heldrak answered well: the Young Kingdoms are pretty il-defined and thinly written.
But we have a few clues nonetheless:
Dharijor is an expansionist state ruled by a king and a small noble class. Cavalry are equipped with horse armour and described as knights. Armour and helmet plumes are generally black although nobles may have more colour and decoration. King Sarasto is noted as wearing dark yellow armour.
Foot soldiers are mentioned in black armour and equipped with halberds. Archers are assumed from the description of a battle involving Dharijorian troops which opens with ‘a rattling black cloud’ of arrows.
Jharkor is ruled by a king and a nobility (although after the death of King Dharmit, Queen Yishana assumes the throne). Jharkorian knights are recorded in gold armour, charging at the gallop with drawn longswords.
Infantry weapons are not described but probably are a mix of bow, javelin and spear. Infantry can be supplemented by camp followers, slaves and serfs. It is not clear whether the latter formed some kind of ‘rising out.’
The White Leopards are an elite guard of 500 picked men who ‘run as swiftly as horses, are as strong as mountain cats and ferocious as blood-mad sharks – they are trained to kill and killing is all they know.’ They are wiped out fighting a rearguard action, in the face of hopeless odds, at the battle of Sequaloris. They fight on foot and are clad in silver armour emblazoned with a leopard.
Tarkesh is a northern state that provides excellent sailors and ships. Galleys are long and low with a single bank of 10-50 pairs of oars crewed exclusively by free warriors. These men tend to be short and dark faced with black hair and beards.
Horsemen are described as knights clad in thick blue armour with red, purple or white plumes and armed with lances. Foot soldiers outnumber horse by about five to one. Infantry weapons are not described but, given the nautical influence of Tarkesh, are likely to be a mix of sword, axe and bow.
Purple towns is an island specialising in trade and ruled by a council of merchants consisting of the nine wealthiest men.
Armour is generally toughened brown leather supplemented by ornate gilded breastplates and helmets. Cloaks and banners are exclusively purple. Some individuals are noted as carrying large axes that require some strength to wield and this may suggest a trained core. Ships crew are generally armed with cutlasses and shortswords.
Shazaar is ruled by a monarchy. Although mostly farmland, Shazaar borders a range of bleak wastelands. Shazaar is famed for its cavalry, ‘wild riders but clever fighters and well disciplined.’ These may be analogous with a range of frontier or marcher forces such as early Norman knights, Anglo-Scottish border horse or eastern European Cossack or Deli cavalry.
Shazaarians are described as wearing bronze armour under grey, brown and black jackets.
Foot troops are presumed to be militia raised from farms with cavalry being provided by retained medium and heavy ‘feudal’ troops supplemented by light horse used to animal herding.
Lormyr, Argimiliar, Pykaraid and Filkhar (southern barbarians): blue and white checked clothing is most common. Breeches and cloaks can also be worn in bright colours, scarlet and green is noted, some of these will be checked also. The clothing gives these forces a celtic flavour which is carried though to the troop types. Some armour can also be checked.
Filkhar is noted for its long handled axes.
Ilmioria is a pleasant land of forest and farmland divided in a number of large city states or Duchies. As suggested, each state is presided over by a Duke supplemented by a council of advisors. The Duchies are bound together by treaties and trade agreements and have formed a national senate. Sorcery is rarely practised and Law is the nominal allegiance.
Fur caps and chequered cloaks are common clothing as are colourful doublets and hose. Ilmioria is also noted for producing fine tooled leather.
Vilmir is a nation dominated by Law. A religious and noble hierarchy presides over a harsh and bureaucratic tax regime. Although nominally headed by a king, the land is often subject to civil war between conflicting noble groups. A reasonable parallel may be medieval England suring the reigns of King Stephen or Richard I but with excessive church influence.
All adult males spend five years in Vilmir’s military, serving in one of five legions. The Grey Defenders are a military elite acting as a combined internal security unit and thought police.
Most citizens wear drab grey with nobles clad in austere white or black.
All of this was found in the HOTT supplement "Wargaming in the Age of Elric of Melnibonē" by Declan McHenry."
