Sentry & Patrol Duty for AI\'s
 

Has anybody out there experimented with the Sentry and Patrol buttons to see what they do?
I am interested in what the AI does with ship that have been set to Sentry & Patrol duties. I would like to setup a scenario with 'relic' ships
that guard systems and maybe patrol several systems. Maybe even roam around the galaxy attacking randomly. Any help would be appreciated!
