It's not createunit.
These units become available under the civilian men list with 6th sense's editor update. When the reporter runs her hands grow funny. This is because her hands are modeled differently (hands behind her back), so it stretches and moves the wrong way.
D_P_ is right, the news reporters are for cutscenes and not gameplay. Probably why most of the units cannot die either. When she is standing still, you can see her hands are behind her back, and she is holding a microphone (on at least one of her units anyway).
So, unfortunatly the only way you can use these is in a cutscene or if she doesnt move.
There are a few other hidden units to like King, North Sahrani Prime Minister, Undead units etc.. they seem to be ok to use in missions.
