Getai/Strategic Overview

At the very heart of the Getai nation is its heavy infantry and cavalry, which consists mainly of well-girt noble infantry (namely, Getikoi Stratiotai, Thracian mercenaries) and Cimmerian units (consisting of Kimmeroi Hippeis and Kimmeroi Arkhigoi). Because the Getai don't really have a lot of mainstream units (albeit they do nevertheless have a few solid ones) it goes without saying that the Getai will have to keep their trade up and running at all times to ensure there is enough Wealth to satisfy their need for mercenaries. 
The main issue with the Getai is that although they have many mercenary units, their cavalry selection is but rather poor, consisting mostly of Balkan Horsemen, Thracian Prodromoi, Tarabostes and finally their Cimmerian cavalry, which still uses vintage neo-Bronze Age accoutrements. The only good thing of these units that can be said is that the Kimmeroi hippeis is a good early-game unit, being fairly effective against early mid-tier units and also being capable of gathering resources whenever it is attacking the enemy's economic structures, but overall the Getai will perform poorly if attacked in open areas with better melee and ranged cavalry, such as those of Macedon or Persia.
