I think that's true, but I like that this site includes a "ESTIMATED MUNITIONS & EQUIPMENT COSTS" section that shows the value of actual, expended munitions which are all one-time costs directly resulting from the war.

Seems like a massive understatement given how much of this war has been shooting down iranian missiles. According to wikipedia, a single patriot missile cost 4 million, and you often have to use multiple to get a succesful shoot down.
