The U.S. military is waiting for clarity from the Pentagon following President Donald Trump's back-and-forth on troop levels in Europe. That's upending the lives of military personnel and potentially costing taxpayers millions of dollars. That's according to two U.S. defense officials who spoke to The Associated Press on the condition of anonymity to discuss sensitive military matters. NATO allies were bewildered in May when Trump said he would send 5,000 U.S. troops to Poland just weeks after ordering the same number pulled out of Europe. U.S. Transportation Command says sending all the equipment to Europe for the canceled unit cost the military $32 million.

U.S. military contractors will need at least three years to replenish stockpiles of three key weapons systems used in the Iran war. That's according to the Center for Strategic and International Studies. The findings released Wednesday by the Washington think tank add to concerns American forces would have limited firepower in any future conflict with China. The weapons are Tomahawk cruise missiles and Patriot and THAAD interceptors that defend against incoming missiles and drones. President Donald Trump's Republican administration is ramping up defense spending and manufacturing. But it could still take years to rebuild inventories because contractors aren't used to producing the advanced weapons on such a large scale.

Defense Secretary Pete Hegseth clashed with Democratic lawmakers in Congress for a second day. At the start of a hearing Thursday in front of the Senate Armed Services Committee, Hegseth rejected senators' accusations that the Iran war was launched without evidence of an imminent threat and waged with no coherent strategy. He called Democratic lawmakers "reckless naysayers" and "defeatists from the cheap seats." He said they have failed to recognize the many successes of the military against the Islamic Republic over the last two months and in other operations since President Donald Trump returned to office.

The White House is releasing details of President Donald Trump's 2027 budget, including a $1.5 trillion defense spending request. That's the largest of its kind in decades. The Republican president had indicated even before the war against Iran that he wanted to increase defense spending to modernize the military. He's also calling for a 10% cut in non-defense discretionary spending. The president's annual budget does not carry the force of law. Instead, it reflects an administration's priorities and provides a road map to Congress, which handles spending issues. But Congress is free to reject it and often does.

A senior administration official says the Pentagon is seeking $200 billion in additional funds for the Iran war. The department sent the request to the White House, according to the official, who spoke on condition of anonymity to discuss the private information. It's an extraordinarily high number and comes on top of extra funding the Defense Department already received last year in President Donald Trump's big tax cuts bill. Asked about the figure at a press conference Thursday, Defense Secretary Pete Hegseth did not directly confirm the amount, saying it could change. Congress is bracing for a new spending request but it is unclear it would have support. Trump says it's a small price to pay for security.

The Pentagon says it's investigating Democratic Sen. Mark Kelly of Arizona over possible breaches of military law after the former Navy pilot joined a handful of other lawmakers in a video that called for U.S. troops to defy "illegal orders." The Pentagon's statement Monday cited a federal law that allows retired service members to be recalled to active duty on orders of the defense secretary for possible court-martial or other measures. Kelly said he "upheld" his oath to the Constitution and dismissed the Pentagon investigation as the work of "bullies." It's extraordinary for the Pentagon to directly threaten a sitting member of Congress with investigation.

The Tomahawk cruise missile has been in the U.S. military's inventory since the 1980s. While slow by missile standards, the cruise missile flies around 100 feet (about 30 meters) off the ground, making it harder to detect by defense systems. The missile also boasts an impressive range of around 1,000 miles and precision guidance systems that make it the go-to weapon for striking targets that are deep inland or in hostile territory. President Donald Trump has hinted that he might give Tomahawks to Ukraine, which could make a key difference for Kyiv in its war with Moscow. While the United States launched Tomahawk missiles almost exclusively from ships or submarines, Ukraine doesn't possess a Navy with ships capable of carrying the 20-foot-long missile.

The federal government shutdown is raising anxiety levels among service members and their families because those in uniform are working without pay. While they would receive back pay once the impasse ends, many military families live paycheck to paycheck. During previous shutdowns, Congress passed legislation to ensure that troops kept earning their salaries. Time is running out before they miss their first paycheck in less than a week. Payday is supposed to be Wednesday, but the House isn't expected to be back until Monday. Support for military families is available through various nonprofits and charities. And some financial institutions are offering zero-interest loans. But families and advocates say that help can only do so much.
