If the US land forces fight on the side of the President, he will prevail. If they fight on the side of a hostile Congress and judiciary, he will lose. Who they support, and the shape of the crisis which determines that, is history yet to be written. As far as who the troops support, that really doesn't matter. Here's a scenario:

You are a USMC captain. Your battalion has deployed to Fort Meade because of a vague "terrorist threat", your mission is to protect the capital.

At 2 am you gat a call from your major that the White House is under attack by terrorists (almost true), that the President and Vice President are missing (true), that terrorists dressed as US forces are moving through Arlington VA (false).

You are ordered to deploy your rifle company to M and 34th in Georgetown and kill anything that moves on the Key Bridge, which intel says is the route hostile forces plan to use to enter the capital.

The internet is down. TV and radio stations are off the air.

Is there ANY chance you will not move out and start shooting at the troops from Fort McNair trying to cross the Key Bridge and rescue the President?

[Alas Babylon!]

Fort McNair is in Virginia?

When did that happen?

Hint: Maybe you mean Fort Myer?

Similar to scenario of smaller community survival as depicted in TV series “Jericho” amidst the various regional political orders vying for ascendance through isolated military factions.
