What is a military helicopter from Tajikistan doing in southern Afghanistan? 

That question has been prompted by conflicting reports about a February 11 crash that killed four Tajik air force officers, including the son of the deputy defense minister, in Zabul Province. 
Tajik state media report the Soviet-era MI-8 helicopter, which belongs to the country’s Defense Ministry, had been ferrying about supplies since May 2011 on behalf of the NATO-led International Security Assistance Force (ISAF). Khovar, the state news agency, said on February 13 that the reasons for the crash are unknown, but that bad weather was likely to blame. A source in Tajikistan’s Defense Ministry told the Asia-Plus news agency that the helicopter crew was delivering “humanitarian cargo to remote mountain villages in Afghanistan.”
But the Associated Press reports that the helicopter was delivering food to US troops on behalf of Supreme Group, a private contractor. Supreme, which supplies military bases around Afghanistan and operates a duty-free food and liquor store for expatriates in Kabul, told the AP that the helicopter was operated by a company called Central Asian Aviation Services. That company’s website is under construction, but lists a phone number in the UAE. 
So which is it: humanitarian shipments or for-profit contracting? The conflicting reports make it seem like someone is leasing state property under the cover of “humanitarian operations.” Either way, it’s unclear if any proceeds are going back into Tajikistan’s state budget.
