I'm not lookin to get all fancy with the edit I just want to put sandbags here and there and add in artilary of sorts(AA gun etc.) or be able to make a King Tiger Tank or Panzerwerfer availble to use on map.:D

That's ussually called a mod. modtheater.com used to have some excellent tutorials so I would start there. The game is based on the Quake3 Team Arena engine but has been heavily modified.

The short answer is you spawn objects in a map start up script, but there is not much point trying to explain more in a simple post.
