Quick possible military patch identification help

[Baltimore]

Hi All,

I know there are some military insignia fans here, can anyone tell me what this patch is for? I'm assuming military but it could easily not be, any help is appreciated!

That is the Triad Emblem of the Fourth Degree of the Knights of Columbus.

Alright, I was off there, I tend to think all navy blue hats with unknown patches are military. Thank you!
