Gah... I was just gonna post the answer to this. However I have a little correction to make about Siv's answer. In
AotC, "1138" doesn't appear in the sand where Padmé Falls, but on the back of the clonetroopers' helmet, abeit impossible to see on screen. Technically it's still there, it's just impossible to distinguish it
As for
RotS...
spoiler:The clone commander's "name" is Bacara, he is serving General Ki-Adi Mundi.
I just wanted to give some more info on this, props still goes to Siv though
