The US Defense Department has a three billion dollar plan to train and equip Pakistan's military over the next live years, US media reported Friday.

The funds would pay for helicopters, night-vision goggles and other equipment and counterinsurgency training for Pakistan's special operations forces and Frontier Corps paramilitary troops, the New York limes said.

It quoted Pentagon officials as saying up to 500 million dollars could come from a yearly emergency war budget that President Barack Obama's administration is to present to Congress next week.

But with some legislators expressing concern over the Pakistan Counterinsurgency Capability Fund, the top US military officer acknowledged that the United States had not mandated enough accountability for the funds. ,

"There hasn't been an audit trail, and there haven't been accountability measures put in place, and there needs to be for all the funds," Admiral Mike Mullen, the chairman of the Joint Chiefs of Staff, told theTimes's editorial board.

"So we're going to do that. For this counterinsurgency money, which is important, it is critical that it goes for exactly that and nowhere else.”

Mullen said the Pakistani military must change its focus from fighting arch-foe India to combating militants and insurgents within its borders. "That's not going to change overnight," he said.
