The US military hires private trucking companies to handle logistics and transportation in Afghanistan. These companies pay "protection" money to the Taliban and local warlords to ensure safe passage of their cargo. It is estimated that 10-30% of the $2.2 billion in contracts goes to these payments, providing hundreds of millions of dollars per year to the Taliban. The largest security company, which protects most logistics routes, employs a notorious warlord to provide security.
