Greece bases its strategy on mostly defense. Their Land and Air power transmission capabilities are incredibly weak and we're talking about a country that doesnt have the ability to refuel. They still mostly use old ancient unarmored trucks as APCs, and MRAP concept is almost non-existent except for the donated ones. For such an army to attempt an invasion in other lands, it means creating its own nightmare. In any case, the possibility of Greek army breaking through the defense line and advancing against the Turkish army is almost zero.
It has been decades since Greek army faced a real threat, except for the exercises and it is not possible for them to predict what their shortcomings or superiority might be or at what point they could overcome against an enemy developing own weapons that are totally technologically unknown by others. Such states have to adapt by taking heavy damage againts armies like self sufficient Turkey, which uses its battle-proven weapons and apply tactics and strategy on different types of enemies and develops it through mistakes, but the ability to adapt is basically a capability that can only be done by self-sufficient countries as well. So the only thing that a state like Greece can do against Turkey is to ask for help 24/7 and sign protection agreements by renting country's land to foreign soldiers.
Considering these conditions, when Greeks want a show, A war with Greece will take place deep inside Greek territory under any circumstances. How deep the Turkish army will go is a matter of the initiative. Dozens of planes or modernizing their tanks dont change anything in the field.
