501st Military Intelligence Brigade Reenlistment Swag Coffee Mug. For many years the brigade headquarters was located at USAG Yongsan in Seoul, South Korea. It’s now at Camp Humphreys In Pyeongtaek. The mug is a whopping 5.25 inches tall and holds two and a half cups of liquid. I have two of these mugs. I’ll list the second one after this one sells.
