The U.S. Army has used up "virtually all" of its highly accurate long-range missiles, specifically the Army Tactical Missile Systems (ATACMS) and Precision Strike Missiles (PrSM), during the five-month war with Iran, according to three sources familiar with the data. This significant drawdown, not previously reported, has sparked concerns about the military's ability to deter adversaries like Russia and China. The long-range munitions, costing over $1 million each, are crucial for striking targets from a safe distance and have been used to attack targets inside Iran. The PrSM is a newer generation set to replace the ATACMS, but stockpiles were already low due to its recent introduction.
