In CK1 the King could call up his vassals troops and they would have to pay for them. This led to the exploit where because their was the no negative-gold for AI and the King didn't pay a dime for his vassal's troops he could wage a war for free.
Secondly, regardless of the realm laws or circumstances the ruler would always demand everyone ready their troops, even if they were a far-flung count in Greenland and they were fighting a 2-province count or they were a count with a duke liege and realm laws that did not allow the king to call directly on those counts.
In reality, the King shared most of the burden for the troops and had much less control over his vassals troops than his own in most types of feudalism. Even when he did have more control, he still couldn't just demand instant mobilization of an entire realm.
Finally on a related note, in early games of CK1 the highest rank/prestiged character took control of the combat before those with the highest marshall skill. Later this was changed to make it so the highest marshall skill would take over because too much mircomangement was happening, even though it wasn't historic and could lead to unhistoric results, such as the marshall getting claims where his liege should. What I would propose would be to make it so the highest marshall score determines the battle odds (the primary reason for brining the high-skilled marshal), but if anyone is of higher station is present all claims and events trigger on them.
Thus your brilliant strategist is only as smart as his reckless misguided warrior liege when he tells him to charge the oncoming knights with the small contingent light infantry who isn't being backed up.
