What Unit of Service is the Portuguese Crest on this green beret?

[Mac the Knife]

Can anyone help me identify the branch of service of this Portuguese Badge? The green beret the badge is on is made of super heavy wool, and it's ribbon has been pulled. The beret is unmarked except for it's size. Thanks for any insight!

nothing on the red background

Definitely an airborne beret from the colonial war era. Let me ask some people about the red background.

[Mac the Knife]

Thank you both! It came from a collection of "elite" unit berets. So, airborne would make sense.

Well I talked to a bunch of Portuguese collectors and they have never seen anything like it (the red background). The badge is for the 1961-66 period, worn by paratroopers and air police (airborne troops belonged to the Air Force).

Some people have suggested that the red background could be for the airborne instructors of the AIrborne Special Groups. But not everyone agrees!

Beezman, Thank you for your follow-up and for asking your contacts! There is so much out there, we can't be expert on them all!
