Anti-aircraft Artillery Thule Greenland patch

[IrishGunner]

This just arrived today - a recent purchase; an un-official patch for the anti-aircraft artillery units posted to Thule Greenland Air Base.

My wife's father was posted here in the mid-50s with the US Army. Unfortunately, he died this past June; I thought it would be a nice thing to assemble some things related to his time in the Army for her.

Of course, I know nothing about this patch and just stumbled upon it while scrolling artillery related objects; I suspect it is from a later period - 60s or 70s. Anyone have any knowledge about these sort of things?

Or anything about the anti-aircraft artillery units at Thule. (I have to check his service documents to see if they have the exact unit to which he was assigned - but they are in Flordia, very far from Poland.)
