Coast Guard!!

The Coast Guard patrols our US coasts and international waters using many transportation to intercept dangerous activity.

These vehicles may include cutters and aircraft.

The Coast Guard also uses their intelligence to intercept dangerous activity.

   Dangerous activity may include drug smuggling and human trafficking.

   Human trafficking is basically slavery like forced labor is only one example (which is ILLEGAL!!!! If you didn't know). 

   Their logo is 2 anchors with a braided rim (picture below) .
