Here’s another take on this:
Riot Stand Down: Obama to Fire National Guard Chief During Inauguration
Obama’s latest move could trigger mass riots, threats to Trump’s life

This is not accurate. If it’s a stupid idea to fire the commander during his deployment, then it’s Trump’s stupid idea. (Or else it’s not a stupid idea at all and has been well planned in advance by military professionals.)
The chief has said he offered his resignation to Trump effective immediately upon becoming president, and Trump accepted it, effective immediately. Trump has also chosen the chief’s replacement, who has not yet been publicly named but who is prepared to take command at the appointed time.
However much he might like it, Obama has no power to do anything after 12 pm on January 20th. If he’s allowed to depart the inauguration ceremony on Marine One (as Bush did after Obama was inaugurated) then it is due only to Trump’s courteous permission. Without that, he can walk.
