Personality: Samuel is an intelligent man with an ego to show it. He believes he can't be wrong (not literately but he acts like it). He's more or less fearless and very aggressive. Life is a game to him and he plays to win. He is always looking for ways test his strategic and combat skills. 

Brief Bio: Sam grew up in a low income area in New York City. He learned from a young age that people respected strength. He would frequently get into fights with other kids. He was good at fighting and he loved it. He got involved with gangs and dealt drugs. He didn't use them himself. He did it to challenge himself to get away with it and the money was a good bonus.
Once he graduated high school and it was time to get a real job Samuel joined the US Army. Shorty after joining he was sent to the front lines of a conflict in an unstable African country. The US was providing aid to the countries government to stop a local warlords attempt to take over. Unlike most soldiers Sam enjoyed warfare. He enjoyed knowing he could die at any minute. On the front lines the US wasn't only force on the governments side. There was also a private military company called Silver Talon. During a joint operation Samuel got to work with some of the members of Silver Talon. Sam loved seeing how they operated. They were far less strict and much more cavalier than the US forces. Also they were better payed. After the OP the commander of the company offered Samuel a job. He couldn't refuse.
As soon as he was able Samuel terminated his contract with the US Army and joined up with Silver Talon. He did very well in the company and was eventually promoted to a leadership role. It was there that he proved his prowess as a commander. The fellow company members were amazed by how calm he could remain in battle and how fast he was able to create new strategies. They gave him the nick name Bullet Time.
Over the years Sam experienced many conflicts in many countries. He and Silver Talon became close. Eventually when the commander retired he took his place. Years went by and the minor conflicts Sam involved himself in began to bore him. He wanted something more dangerous. Something more grand. Then UNKRCI was formed and Samuel saw his chance. He immediately offered the services of Silver Talon to the group. After all they were a UN force which was low on man power. They needed PMCs to operate effectively.

other: no brown M&Ms. Samuel trained himself to fly a helicopter. He deemed this a necessary part of leading his troops. Having an overhead view put things into a better perspective. Also he wouldn't want to sit off in some bunker giving his men orders via radio. He needs to be close to the action.
