The military would NOT support a third term for Trump. They swear to uphold the constitution and the constitution clearly says no president can serve for more than two terms. Same with any other tricks they try to pull that would let Trump still be president in 2029.
That’s the assumption and I hope it’s correct. We are in uncharted territory though. He’s been actively purging non-loyalists and punishing his foes. This is the dictator playbook and my fear is that he will be completely entrenched by the time anyone realizes he needs to be forced out.
The dictator playbook can't work with the way the US military is structured around loyalty to the constitution and not a person and Trump can't change that. I would estimate 90% of all officers despise him and basically none of them will support him in blatantly violating the constitution.
