I asked chatgpt this very question and here is the AI response, if you are interested:
Good questions. Yes — Donald J. Trump has repeatedly promised what amounts to a “big army” or enforcement force to deport undocumented immigrants.
The Washington Post+3The Associated Press+3WTOP News+3 But the situation is more complicated in practice. Here’s a breakdown of where things stand (as of now):
What Trump has said: promises of mass deportation + use of force
- During his 2015–16 and 2024 campaigns, Trump promised that the U.S. would round up the estimated 11 million (or sometimes more) undocumented immigrants living in the country, deport them, and do so “humanely.” The Washington Post+2Wikipedia+2
- He said that this was a priority — sometimes criminal immigrants first, then possibly broader sweeps later. The Washington Post+2NPR+2
- He also explicitly said he would use state and federal forces — including the National Guard, and, if needed, the military — for immigration enforcement. CityNews Halifax+2WTOP News+2
- After the 2024 election, he confirmed intent to declare a national emergency to enable a “mass deportation program,” commenting “TRUE!!!” to a post stating the future administration would use military assets for deportations. ABC News+2CityNews Halifax+2
So yes — the rhetoric and promise of a massive enforcement force (sometimes described as a “deportation force” or “army”) has been real and repeated.
What’s uncertain or unfulfilled so far (or what faces obstacles)
- Although Trump talks about using the military — likely via the National Guard and possibly federal troops — domestic deployment of the U.S. military for widespread civilian law enforcement is restricted by laws such as the Posse Comitatus Act. Many experts argue that large-scale military deportation raids would face serious legal challenges. NPR+2WTOP News+2
- Operationally, deporting millions of people — many of whom have lived in the U.S. for years, sometimes decades — would be a massive logistical challenge: finding, detaining, transporting, and deporting them would require enormous resources, detention capacity, and likely foreign-country cooperation. The Guardian+2CBS News+2
- As of now, there’s no public evidence that a “big army” — in the sense of a fully mobilized, massive military or paramilitary force dedicated solely to full-scale deportations — has been rolled out. There have been enforcement actions under federal agencies (e.g. arrests/deportations under U.S. Immigration and Customs Enforcement (ICE)), but nothing approaching the scale implied by campaign-trail mass-deportation rhetoric.
- During the same periods Trump has also launched initiatives encouraging “self-deportation”: e.g. under his administration the agency replaced one migration-entry scheduling app with another that includes a “self-deportation reporting” feature, and the government has promoted leaving voluntarily as an option.

Was the “army” just to pressure people to self-deport?
That is a plausible interpretation — part of the strategy seems to be signaling strong enforcement to create pressure or fear, which could encourage some undocumented immigrants to leave voluntarily rather than wait for deportation raids. The “self-deportation” push (via policy changes and an official app) appears to supplement or partially substitute for enforcement.

However, Trump’s own statements often frame enforcement/deportations (not just voluntary exits) as central: he has explicitly promised sweeps, deployment of national guard or military, and mass deportation initiatives — not just a passive “we’ll wait and you can choose to leave.”

In short
Yes — Trump promised a big enforcement apparatus (“army” / deportation force) to deport undocumented immigrants. That promise was serious and repeated.
But implementing such a plan — especially at a mass-deportation scale — is fraught with legal, logistical, political, and practical barriers. So far, there’s no public evidence of a “full-blown deportation army” being deployed; instead we see a mix of enforcement by immigration agencies and efforts (like “self-deportation” tools) that may rely on pressure to leave “voluntarily.”
