Air Force

One of the five main branches of the US military that was founded on September 18, 1947. It serves a vital function in combat (as I am certain you have heard about drone strikes) and is often called in when too much shit hits the fan. Despite it's importance, it remains the second least respected branch of the military

At least the Air Force receives more respect than the Coast Guard
