Yes. Members of the National Guard have been deployed, and government officials have publicly stated their intent to deploy additional forces.
From the Wikipedia page on the US National Guard [1]:
> The National Guard is a state-based military force that becomes part of the U.S. military's reserve components of the U.S. Army and the U.S. Air Force when activated for federal missions.
The National Guard constitutes military troops under federal activation.
SirSavary's comment covered the military deployments so I will just say that there are numerous cases of the Trump administration deporting people without due process outside the country to places like CECOT where they are tortured. I don't think even the Trump administration denies these things.
