Release the Devil Dog from Hell: Male OC x Rainbow Six Siege

(A/N: Oh boy... A Rainbow Six Siege story from me! This is going to be very interesting.)

The White Mask... It is a terrorist organization. Their motives are explicitly unclear, however, they are known to execute attacks anywhere in the world. They do not care about race, religion, age, gender, and nationality; they just want to spread chaos in the world. The organization has become a big enough threat to the point that the Rainbow counter-terrorism program has been reactivated. Team Rainbow consists of multiple counter-terrorism units, such as the FBI, GIGN, SAS, GROM, etc. However, they are willing to take more units. Fortunately for them, there is one individual that accepts a position in the Team. He is not from any of these units; he's from the United States Marine Corps. His name is... Jonathan "Devil Dog" Anderson.
