The idea of the heroic king fighting on the frontlines is a giant load of bullshit that was (and still is) used to manipulate the masses. Even back when we were walls of spears smashing our pointing bits into each other, officers (so nobility and government) would hang back. Because you need someone who can coordinate the battle (to the limited extent they could) and sound a retreat (or flee).
Even modern day middle manager officers are pretty safe either back in the command tent or off to the side so that they can hear the radio and coordinate support.
And if even the Colonels are on the front line? Something has gone HORRIBLY wrong.
This “member when our leaders would actually fight for us” is the kind of bullshit that leads to strongman fascists… like netanyahu.
