CLAIM: 'As of today, there is not one member of the United States military who is an active duty in a combat zone, in any war zone around the world, the first time this century.'
Fact check: False
Harris appears to be using a narrow definition of what constitutes a combat zone, because there are U.S. military troops in the Middle East who have come under deadly fire over the last year.
There are currently 2,500 U.S. military troops in Iraq and more than 900 U.S. military personnel in Syria who are on a mission to support local forces to prevent a resurgence by ISIS. While the troops in both countries are mostly involved in an advisory role some of them are also engaged in risky counterterrorism missions against ISIS.
But the real threat to these troops over the past year were the repeated attacks against U.S. bases in both countries by Iranian-backed militia groups that launched more than 170 rocket and drone attacks. But it was an attack on a U.S. base in neighboring Jordan this past January that has proven to be the most costly. Three U.S. Soldiers were killed and 34 others were wounded when a drone launched by those militia groups made it past air defense systems. That attack led the Biden administration to order large-scale retaliatory airstrikes against the Iranian-backed militia groups.
