Where is the command menu

Hey,

First I want to say that I am german and maybe my grammar could be incorrect.

I am having a DayZ Server and I added some AI units to my player group, but there is no command menu. Normally you can select with spacebar the units and give orders, but that does not work for DayZ. I think that is repressed by DayZ. My idea, I would add the command menu manually. But I can not find it into the arma pbo's.

Thats my question, where can I find the files for the command menu.
