Countries to consider:
Egypt
Israel
Turkey
Iran is out because too outdated equipment. Rest not even close.
Egypt
+ battle experience, large and modern tank fleet, strong air defence, big man power pool
- during the wars commanders showed very little initiatiave, misinformed their higher commanders this resulted in very poor offensive capabilities and reaction to changed situation.
Israel
+ most experienced in all types of war: conventional, blitzkriegs, large scale tank battles, urban warfare, combining forces, UAV coordination etc... High quality of personnel (in Israel bulk of the combat units are people from middle-high class, in other ME countries they tend to avoid army), modern equipment, including some unique for Israel like long range ATGM, APS. Most developed indigenous industry.
- small man power pool (needs to rely on reserves), high public sensitivity to casualties.
Turkey
+ large NATO standard army, big man power pool.
- equipment mostly old, virtually no conventional war experience.
