Yes, I wouldn't trust using a credit card on the ISPs located in Afghanistan. I've also heard about people getting money stolen from them while they were at the PX on KAF (Kandahar Air Field). There were charges they had not made being sent to the Phillipines I believe. However, I bought things many times there and never had an issue. Just be sure to check your LES and bank statement often.
Strange, I have a funny story about a cow and a child as well. It involves a 240B. There was this little girl who couldn't have been much older than 10 that we would see almost daily herding her cows to the river. She never seemed to mind us and would always wave. One day while she was letting the cows drink, one went too far into the river and must have got stuck. She tried everything to get the cow out of the water. Yelling at it, hitting it with a stick, throwing rocks, cow would not budge. The cow didn't seem to care even though it was up to its neck in water. Seeing this, we motioned for her to get away from the cow and the had the gunner on our lead vehicle fire a 5 round burst next to the cow. It was out of the water faster than I got my hearing back.
