Yes, he would be the WORST marshal possible.
But they could command not only his unit, but much more!... BUT with a 'malus'.
He could command an army of 4 units, but with a 'acceptable' malus of -15%! ...Or an army of 8 units with a horrible -35%... etc...
He would be a really bad choice for Marshal!
But he could 'do the work'... and not bad for a noble with NO 'military experience' (as 5% is the initial value for the Leadership... I think).
