i notice that for some units the unit descrition is ether not their or not spelt very well, i would be wiling to correct these and add these descriptions if you woud like, i will write them in text format and then ether post them here or pm you and you can add it for the next update, let me know if you want me to help you of course.
for a little sample ive done some of the roman units.
roman swordsmen "The Roman field army relied on its heavily armed comitatenses to cut down the enemy, much like Caesar legions of the past. However the Romans soon realised that they needed a lightly armoured unit that was cheep to train and equip to back the comitatenses up in the field. This led to the creation of the roman swordsmen, these troops were armed with poor quality chain mail armour usually poorly maintained and rusted and blunt swords and thin helmets. These troops where easy and quick to train and where used on the front line of a field army to absorb cavalry charges and enemy artillery so the comitatenses can then cut the enemy down."
gothic spearmen "The Romans always hated the culture of the barbarians, however they where all to willing to import foreign fighting methods into their own if they felt it was effective, this lead to the creation of gothic spearmen. Recruited from the eastern empires boarder with the Goths the gothic spearmen are heavily armed spearmen that are trained to form a shield wall, they are a great defensive force and good against cavalry but they lack the commitment and dedication of the main roman army and are venerable to artillery."
what do you think? if you would like id be more then happy to do it for all of your units that lack one and id fix the spelling for the ones you have done yourself.
