Probably, if Trump doesn't activate the Insurrection Act, nobody else will do anything in a big way.
The time is near where Trump will have to activate the Insurrection Act, or otherwise forget it.
Soldiers follow orders. They are taught to not question the ethics or reasons, or even to know them.
If the Insurrection Act is activated, it will be based on Trump's 2018 Executive Order. So, there will be enough proof for any military people who need it.
I think Trump should acknowledge that Biden will be President in January (even if illegitimately) and start his 2024 campaign.
