Nope. They were different in 66 and 67. There was no swamp rat patch only the 119th company patches and the 545th patches. They were not joined together as the 119th yet and the term "swamp rats" did not exist. The 545th was a TC detachment attached to the 119th. It was one of the early army aviation "KD" detachments assigned to go with TC aviation companies on extended deployment to augment the company's 'Service platoon" capability. The 545th TC det Patch was red with a bucking Huey and a knight with shield on it holding a screwdriver. The shield had 545th on it. I have one somewhere in my junk box.
