A.J. Bruce is an agent with the CIA. Javier Smith is a Colonel with Delta Force.
While they each have their own normal chain of command, they are brought together in the first recorded adventure as the Agency worked on a credible threat tip regarding ISIS and its new corroboration with Columbian drug cartels. Bruce and Smith meet in a briefing at Langley where Bruce's boss, Robert Lintstone, introduced Smith as an advisor and Bruce as his 'troubleshooter'. Smith will quickly but respectfully point out he was not there just in an advisory role. Bruce does not challenge her designation as she knows it is more than justified.
Bruce is a fairly tall, 5'10", quite athletic woman with long, brown hair. At 40 years of age, she has been with the Agency for more than enough time to have already created a reputation, looked upon favorably most of the time, as an independent, highly capable operative. Bruce is adamant at their initial meeting that she works alone; to her annoyance she is immediately overruled. In addition to her impressive service record, she has also been able to earn a Masters Degree from Georgetown University.
Javier Smith stands 6'4" with a thin scar running from his left ear to his chin, piercing green eyes and olive complexion. He is understandably proud of the fact that he still had washboard abs considering he is 45 years old. His hair is still black though streaks of gray are starting to show. Smith lets Bruce know early on that he is planning on retiring from the military; he still craves the action just as she does but he knows with his exemplary record, a star would soon replace his eagle and as he puts it, "I'm a field rar, through and through. Sticking me behind a desk in the Pentagon is like a prison sentence". He leaves the military with a promise from the Chief of Operations that when he starts his own company, a good deal of business from the Pentagon would be coming his way.
The two will have, as expected, a few getting-used-to-each-other issues at the beginning but it will not take long before both learn just how good the other is. And before they realize how close they have quickly gotten.
