Angel Garrison

Angels operate in garrisons, which are units or divisions in the Host of Heaven. Angels collectively contribute to the affairs and take part in activities assigned to their garrison. Every angelic group has its own leaders and supervisors that are separate from the archangels.

So far, only Castiel's garrison has been mentioned.

Castiel's garrison

Castiel was a member of a garrison led by Anna Milton. Upon Anna's departure from Heaven, Castiel was given the position of leader in her stead. This particular garrison was assigned to watch over humanity for 2,000 years, without news or word from their superiors or God.

Four months after Dean Winchester went to Hell, this garrison was assigned with the task of retrieving his soul. They launched a crusade and successfully retrieved Dean, with Castiel being the one to personally resurrect him. Castiel was then ordered to guide Dean through tasks delivered to him from Heaven.

Unfortunately, Castiel's growing attachment to Dean led to his demotion and Uriel's promotion (though whether he became garrison captain is unknown). Later on, at Dean's insistence, Castiel would abandon the Host of Heaven and side with the Winchesters in a bid to stop the Apocalypse. He presumably regained his former position in the garrison once the team succeeded.

Following the outbreak of the Leviathans, Hester was said to have taken charge of the garrison, only to lose this position when Meg killed her to protect Castiel. Castiel himself mentioned sometime later that his entire garrison had been wiped out, or that some of the members had gone into hiding. He has not mentioned them again since.

Known members

• Anna Milton (formerly) (deceased)
• Castiel (formerly)
• Uriel (deceased)
• Bartholomew (deceased)
• Seven unidentified angels (deceased)
• Inias (unknown)
• Hester (deceased)
• Balthazar (presumably) (deceased)

While it is clear that Anna was the garrison's former captain, it is unknown what other rankings existed in the garrison. Uriel was a subordinate of Castiel up until the latter was deemed too attached to his charge (Dean), and was subsequently demoted. Uriel was also responsible for the death of seven garrison members, one of whom was shown at the beginning of On The Head Of A Pin.

Zachariah was shown to be a superior of Castiel. Whether he held a higher rank above Anna or other angels remains unclear, as his exact rank is never explicitly stated.
