The marker addon
http://www.ofpec.com/editors/mods/CoC/USMCsymbols12.zip
is absolutely essential and goes into your addon folder.
This is the only thing you need to play any of the missions, i.e. either the Battle School missions or the Tutorial mission. These go into your missions folder.

The editing package (at http://www.ofpec.com/editors/CoC.php referred as "CoC Command Engine") is only needed if you want to create your own CoC missions. Take a look at the accompanying editing manual for an explanation how to do this.
