A memorandum of understanding on "Afghanization of special operations on Afghan soil" will be signed later Sunday by Kabul's Defense Minister Gen. Abdul Rahim Wardak and the commander of U.S. forces, Gen. John Allen, the Afghan Foreign Ministry said in a statement.
Details were not immediately released, but the name of the memorandum suggests that it will apply to a range of quick-strike raids in villages, not just nighttime operations.
A U.S. military spokesman in Afghanistan confirmed that the agreement would be signed Wednesday but declined to go into details.
"The document will formalize a lot of what we've already been doing as far as special operations," said Col. Gary Kolb. "All the special operations will adhere to the Afghan constitution and comply with Afghan law."
Night raids have been a constant source of tension between the Afghan government and U.S. military. Afghan President Hamid Karzai has called previously for all international night raids to cease, saying that they are provocative when carried out by foreign troops. The U.S. military has said such operations are key to capturing Taliban commanders.
More than 97 percent of night operations are combined operations involving Afghan forces and almost 40 percent of night operations are now Afghan-led, according to the Pentagon. Also, 89 percent of night operations occur without a shot fired and less than 1 percent result in civilian casualties, the Pentagon says.
However, it's unclear whether Afghan forces have had much authority even in operations that are nominally "Afghan-led." Sometimes this designation means only that an Afghan soldier is the first one through the door, or that officials have given a rubber-stamp to the mission just as it starts.
Officials briefed on negotiations have said that the deal is likely to involve a compromise in which Afghan military units would take a larger role in planning and carrying out the raids, and an Afghan judge or panel would have a say, if not full veto, over the operations.
The agreement would be a key step toward finalizing a long-term partnership to govern U.S. forces in Afghanistan after the majority of combat forces leave in 2014. The long-term pact is seen as important for assuring the Afghan people that they will not be abandoned by their international allies.
"It opens the way for the for the signing of the strategic partnership agreement which we hope our two presidents will be able to sign in the near future," said Janan Mosazai, a spokesman for the Foreign Ministry. Both U.S. and Afghan officials have said that they expect to sign the full partnership deal in time for a NATO summit in Chicago in May. The issue over the conduct of night raids had been a major sticking point.
The night raids deal follows an earlier memorandum signed on the transfer of authority over detentions to the Afghans - another issue that had threatened to derail the strategic partnership talks.
The detention pact sets forth a timetable to give Afghans operational control of facilities used to hold Afghan detainees, but leaves decisions on who to release to a panel that includes American military officials that must come to a consensus before any detainee is let go - essentially giving the Americans the ability to veto any release.
There may be similar fine print in the night raid deal that would allow U.S. forces to maintain a significant level of authority.
It's unclear if a higher level of Afghan authority will actually mean that the targets of raids will be treated more humanely. There have been instances of villagers complaining that when Afghan forces conduct raids they also loot houses. Also, the U.S. military stopped transferring detainees to a number of Afghan prisons after the U.N. discovered evidence of torture at the facilities.
