my mistake, not the US Army but the CIA (being guarded by the US Army)

The CIA Gave Karzai Bags Full of Cash for Over a Decade
Afghan president Hamid Karzai has a sugar daddy, and its name is the Central Intelligence Agency. Or at least it had a sugar daddy.
Afghan president Hamid Karzai has a sugar daddy, and its name is the Central Intelligence Agency. Or at least it had a sugar daddy. For over ten years, American spies greased Karzai's palms about once a month with suitcases, backpacks and even plastic grocery bags full of cash. And not those relatively worthless Afghanis either. According to a New York Times investigation, the CIA delivered tens of millions of dollars in cash right to Karzai's office. "We called it 'ghost money,' " Khalil Roman, Karzai's former chief of staff, told The Times. "It came in secret, and it left in secret."
Evidently, that's exactly what's happening in Afghanistan. "The biggest source of corruption in Afghanistan was the United States," an America official said to The Times. To give you a sense of the scale of corruption, the only other country found to be delivering bags of cash to Karzai was none other than Iran. And what do we get for all that bread? Officials on both sides say that "the agency.s main goal in providing the cash has been to maintain access to Mr. Karzai and his inner circle and to guarantee the agency's influence at the presidential palace, which wields tremendous power in Afghanistan's highly centralized government."
