Here is a rough draft since I have time on my hands.
Sorry if the style and English is not great but right now I'm having a slight fever

Name: William Carter
Role: Former Agent/Squad Leader
Affiliation: Former CIA/Rogue Agent
Details:
After serving in the Pacific theater during the Second World War he started working as a field operative for the CIA in 1948.
It is presumed he defected to a rogue association of agents while being on an assignment in the U.S.S.R.
He then set up a house fire at home killing his entire family to fake psychological trauma
This way he got a post in the CIA's administration, where he went on to gather trust and intel.
He is implicated in several attacks on US military facilities in the 1960s. The first being the destruction of the Groom Range facility and at least participation in the assassination of J. Edgar Hoover.
Reports claim that his group used advanced weapon technology suggesting that it operated on a world wide scale with large amounts of funding from the shadows.
In the following weeks he played a major role in several Kidnappings of scientists, engineers and military personnel as well as bloody raids on civilians.
There were findings that interrogations took place, where he also took part in the torture of abductees.
One report details a long vertical cut in the face of one of his victims.
During a raid on the main hideout of aforementioned association he was wounded.
It is still unclear what happened to him afterwards.
There is a strong possibility that he escaped, taking some of the advanced technologies with him.
If that is the case it could be that our enemies may have access to those.
