The US handed over the Camp Kearney base in Paktika Province to the Afghan government in 2014, with an estimated $8 billion in equipment still inside. Today, the estimation is that about $1 billion worth of equipment is left.
So what happened between then and now that cost the site about $7 billion? Mass looting. The provincial governor says that former governors, local mayors, MPs, and commanders have all had a go at the site, and everyone has been entering the base and taking anything that isn’t nailed down.
