OGR Coop mods can be played online with your friends, or by yourself by following this guide.

Installing an OGR coop map packaged in a zip archive (zip file)

Extract the contents of the downloaded zip file. You should have a .bundle file and a .bundle.log file, put both of these files in the custom_levels folder in your GRAW installation.

Installing an OGR coop map packaged in a executable installer (exe file)

All you have to do with an installer is make sure it points to the GRAW custom levels folder. For example if your games are installed on drive D: it should look like this.

d:\Program Files\Ubisoft\Ghost Recon Advanced Warfighter\custom_levels

Summary

What you should end up with is a pair of files for each OGR Co-op map, placed inside your custom_levels folder - see the image below for an example of 3 installed OGR mods.
