I only know one story of "delta force" from my friend in the military. My friend got a crappy shift stationed at a small exit gate on a base in Iraq. It was around 2am and 4 atvs were trying to leave the base with duffel bags. These people on atvs had no badges in a black unmarked uniform with balaclavas on. My friend kept the gate closed. They spoke down to him yelling at him to open the gate in some kind of hurry. They refused to show any orders. My friend took his machine gun and pointed it at the first guys forehead. These guys were not leaving and were about to get shot. He had shot people before at the gate and he moved his index finger onto the trigger. My friend demanded to know what was in the duffel bags, see orders and ignored his radio. The men on atvs demanded him to answer his radio. My friend was getting ready to open fire. The first guy on the atv saw this wasn't going well - tried to calm things down - and opened a duffel bag. It was cash. 4 atvs carrying 20+ duffel bags of cash. Luckily for my friend, he finally answered his radio, and it was the base commander ordering him to let the atvs out of the gate. He let them go. The 4 atvs drove off into the night with duffels of cash. He referred to them as "spookes" - and this scenario was quite common after that.
