How do I get my Garrison Barracks to level 3 ?
To get your garrison barracks to level 3 you must send your garrison followers on special patrol missions. This is done by using your Command Table in your Garrison Town Hall. You want to look for missions that have a spyglass to the left of the mission name. The missions will be of different levels from 90 to 100 and they must be completed without failure. The patrol missions will take from 30 Min to 10 hours and 1 to 3 garrison followers. After you have completed all the patrol missions you will be rewarded the Achievement Patroling Draenor. The Patrolling Draenor Achievement will unlock the Garrison Blueprint: Barracks, Level 3. After leveling up your garrison barracks building to level 3 you will gain 5 more usable followers, grant access to racial guards and banners.
Look for the Spyglass on the left side of mission name. Make sure to select the correct followers for each patrol mission so that you can complete the missions without failure.
