Using Great Seljuk Empire in MEG
The army, at least in my hands, is a shoot, soften the enemy up, fall back and repeat until you can make a hole in or weaken the enemy formation to the point where a charge by Mamluks or Kurds can crack the battle open.
Flank marches with the Turkoman cavalry are an option but if done reuduce the on table force significantly.
Troops and suitable miniatures
My army is made up of Outpost miniatures, they are hopefully suitable for the Seljuk Empire but also double up as generic early medieval Arabs.
