The Iranian military spokesperson said that they are shifting from frontal combat to distributed warfare.

(It's nothing more than having no frontal assault capability, no air superiority, no sea control, and no powerful ammunition counterattack capability. The so-called distributed warfare is just leaderless guerrilla warfare. Staple food and cooking oil are both imported. The key to a protracted war is the popular base and food supply, both of which are lacking. The only ace card is to blockade the Strait of Hormuz.)
