Experts have warned that the US could find itself insufficiently armed for a future conflict. US forces fired more than $22 billion in munitions fighting Iran this year, draining critical weapons stockpiles in the process, a new Defense Department watchdog report says. The Pentagon inspector general's report, which was published Monday evening, estimated the cost of Operation Epic Fury , which began on February 28, to be $33.4 billion as of June 29. That tally includes $22.3 billion for expended munitions.
