They left a shitload of up-armored vehicles that Democrats were bitching to GWB about, saying that he didn't care about the damned troops.Wrong.
That was $5 billion worth of equipment, in 1973. Adjusted for inflation, that was $30.4 billion worth of equipment today.
So yes, far more was left in Vietnam than was left in Afghanistan.
To just give an idea, the most advanced fighter of the Afghan Air Force in 2021 was around 2 dozen Super Tucano's.
In South Vietnam, the US left the South Vietnamese Air Force over 300 A-1 Skyraiders. Almost 200 F-5 Tiger fighters. Over 150 A-37 Dragonfly fighters. Plus around 800 cargo aircraft, and over 650 helicopters. We left enough equipment to give South Vietnam a fairly modern military force.
Mostly what we left in Afghanistan was the dregs that they did not want to bother to bring back.
In less than a month they were driving them in Tehran.
I hear they also left a shitload of night-vision equipment.
