Logan Gregory

'Logan Gregory' was an ex-military officer who worked in Sigma Force, as the second-in-command.

He was the second-in-command to Sean McKnight and later Painter Crowe.

Map of Bones
At this time, he was the operations manager for the time being. He had been the tipping point for the Dragon Court, as he was a mole, all the while keeping a low profile. He was caught after painter Crow pieced together the evidence and determined it was him. Although it was not directly mentioned, it is implied that he was the mole. However, he was cleared.

Black Order
In Black Order, it was not him and he still worked in Sigma Force. He had called Grayson Pierce early in the morning, for Grey, and told them they need something.

He was the center point of contact for people to information. Painter was in the Himalayas and received the distress signal Painter had sent out. There, he had sent airplanes and men to deal with any threats and had Painter Crowe evacuated.

Later, during the missions, he was sent with Kat Bryant to visit the Ambassador of South Africa in washington D.C. To glean any sort of information about the Waalenberg family. The ambassador showed them information about the Waalenberg family and how they they are prosperous in the world. He also shows them one thing, a bell that was gifted to all embassies around the world. One of them was a bell. A moment after the bell was introduced to Logan, the specialized technician came in from the elevator and opened fire with a firearm, killing Logan on scene.

A few days later, a military funeral was held for Logan with every member of Sigma Force in attendance. He was mentioned a few times in later books.

Appearance
He appeared more a California surfer than a leading strategist: blond hair, tanned, fit but going a bit soft in the belly.
