Military leaders raise concerns over Iran operation

Senior US military leaders have warned Defense Secretary Pete Hegseth that the prolonged military operation against Iran risks weakening the armed forces' ability to respond to threats elsewhere, according to people familiar with the matter. The warning was detailed in the August 14 edition of the Secretary of Defense Orders Book (SDOB), a classified document that tracks the worldwide availability of US warships, aircraft, personnel, and weapons systems.

The heads of the Army, Navy, and Air Force, along with the four-star commanders overseeing US operations in Europe, Asia, and Latin America, raised concerns about the strain the prolonged operation was placing on troops, equipment, and military readiness. One person familiar with the matter said that US military leadership believes the war in Iran has been "too much for too long."

The SDOB, typically produced twice a month, also reflects the president's priorities for the armed forces, which the defense secretary and the branches of the military carry out. At the time of the assessment, US Central Command had more than 50,000 troops on alert in the region as President Donald Trump continued to demand that Tehran reopen the Strait of Hormuz and accept US terms for ending the conflict.

Orders to extend deployments draw objections

The August 14 orders book directed some forces in the Middle East to remain deployed through September and others into 2027. That prospect prompted several senior commanders to formally object while saying they would carry out the orders. According to The Washington Post, the Navy's top admiral, along with the leaders of US European Command, US Pacific Command, and US Southern Command, responded with "non-concur," meaning they do not agree with Hegseth's order but will execute it regardless. Leaders from the US Army and Air Force also noted that the extension of their forces comes with significant risks.

Adm. Daryl Caudle, chief of Naval Operations, told Hegseth that the Navy could not sustain its current level of support for the Iran conflict because there was no anticipated end date, according to people familiar with the assessment. Caudle also indicated that barely one-fourth of the Navy's destroyer fleet was ready to deploy, a sharp decline from prewar levels. At a recent event in Norfolk, Caudle described the deployment extensions as "very challenging for our sailors." He said, according to a Navy transcript: "I typically am not a big fan of extensions, and I push back hard on that, but the enemy gets a vote."

The commanders of European and Southern commands warned that providing ships and surveillance aircraft to Central Command had degraded their ability to fulfill homeland-defense responsibilities. Adm. Samuel Paparo, head of Pacific Command, objected to the level of support his command was continually required to provide, including an aircraft carrier strike group and destroyers.

Strain on forces and equipment

Elements of the 82nd Airborne Division, which mobilized 2,000 soldiers in March in response to the Iran war, were set for deployments lasting up to a year. The prolonged war has also depleted key US military stocks, including Patriot and Terminal High Altitude Area Defense interceptors, as well as long-range Tomahawk missiles. About 25% of the Pentagon's Reaper drone fleet had also been lost, while US bases in the Middle East had suffered billions of dollars in damage, according to earlier reports.

The Trump administration has rejected reports that the US is facing significant munitions shortages.

Pentagon response

Pentagon spokesman Sean Parnell said in a statement that decisions regarding the scope and duration of specific force commitments to any Combatant Command are made based on the current threat assessment, strategic priorities established by the President, and the advice of the Chairman of the Joint Chiefs of Staff and Combatant Commanders. Parnell added that the Pentagon does not discuss internal operational processes, such as the SDOB, or specific concurrences, non-concurrences, or risk assessments provided by the Services or Combatant Commands during force allocation.

The conflict with Iran has entered its sixth month, according to the assessment, with no end in sight for US military involvement in the region.
