The cost of future deployments is “highly uncertain, mainly because the scale, length, and location of such deployments are difficult to predict accurately”, Swagel wrote.
If current deployments are continued, “that cost would range from about US$6m a month for 350 personnel in New Orleans, to US$28m a month for 1500 personnel in Memphis, to US$55m a month” for those in Washington, he added.
In addition to domestic deployments, Trump has repeatedly employed military force outside the US since returning to office for a second term a year ago.
In the Middle East, he ordered an air campaign against Yemen’s Houthi rebels and strikes on Iranian nuclear sites.
Closer to home, US forces have targeted alleged drug-smuggling vessels off South America and seized the leader of Venezuela and his wife.
