It seems to suggest so, but you have to take also into account all the violations that never occur because some honorable human soldier choose to disobey direct orders from their not so honorable superiors. Or the much more extensive and systematic violations that ruthless but pragmatic commanders never order in the first place because they are aware on the effect that would have on the morale of the troops.
You are right, and of course in most cases we won't know of such cases, so there is no way to judge how many there might be.
On the other hand, robots would also complicate things for the not-honorable superiors -- for one, they'll lose an option to give verbal orders and then claim no knowledge and blame subordinates when things come out -- they would now need to alter electronic records.
But my point is just that the effect of higher robot involvement is far from clear.
