Yeah it sounds like a large scale attack is coming, and more weapons and fuel right after. But I think this is at most a 2 week supplies.
Honestly I don't see how Iran as it is right now last a month. It even looks like the Kurds might get involved which means another front for the IRGC to fight.
Here's the breakdown of Iran's strategy which I read in an article
Aim - Revenge (Hoisting red flag was clear indication) and Survive. It's because of this I told you yesterday that America possibly set itself as a target of future extremism
Strategy
Iran's military strategy firstly focuses on “asymmetric endurance, which is a case of hardening ‘missile cities’, dispersing command structures, and accepting initial damage in order to preserve a second‑strike capability rather than trying to prevent all strikes”.
Missile cities are defensive infrastructure used by Iran to safeguard its ballistic and cruise missiles from any aerial attacks
Regional saturation and proxy warfare are also part of the strategy whereby Iran is using “large salvos of ballistic missiles and loitering munitions, alongside actions by Hezbollah and remaining partner militias across the Middle East, to stretch Israeli and US missile defences and impose costs region‑wide.
Iran has also threatened to close the Strait of Hormuz as part of its military strategy to raise the global economic stakes of the war and pressure Western and Gulf governments. Targetting commercial and energy infrastructure revolves around this aspect.
Stockpiles
Reports are suggesting that Iran's has huge numbers of missiles (including ballistic) and drones still left and they have expanded their production in last few years. They have strong army as well.
