The U.S. and Israeli militaries launched large-scale combat operations against Iran this weekend. U.S. President Donald Trump said the strikes, which are designed to prevent Iran from obtaining a nuclear weapon and reduce its offensive missile capabilities, could continue for four to five weeks -- and perhaps far longer.

U.S. and Israeli forces are expected to use an extensive array of ordnances during this time. Much of these armaments will need to be replenished in the months and years ahead.
