There doesn't appear to be a way to place strike commandos, heavy commandos, mortar trucks or intrepids in the blitz mode map editor, even though warmachines can build them. In the blitz mode editor, the rock formation terrain is on page 2 of the terrain tab, even though all of the terrain could be on one page. The buildings tab in the classic mode editor is barely on the screen.
Also, why can't there be maps with both buildings and warmachines? That seems like an artificial limitation.
