Read history, angels fought with Muslims in Uhad and other battles and people saw them and enemies quit the battle as they couldn't believe it and they were so scraed which gave Muslims the vitories despite the fact that they were 4-5 times less in numbers. I think same is happening in Afghanistan.
In the supernatural thriller THE OBJECTIVE, Daniel Myrick locates the action in a remote mountain region of Afghanistan, where a team of US Special Ops forces is dispatched with the ostensible orders of locating an influential Muslim cleric. While on the mission they find themselves lost in a Middle Eastern 'Bermuda Triangle' of ancient evil and faced with an enemy that none of them could have imagined.
