Con Duggan and Steven Dye are assassins for the CIA.
As the President grew more and more angry with the evil about the world, causing trouble not just for his country but for the rest of humanity, he desired a way to strike at them one by one. When he heard of a incredible new rifle capable of killing from a far distance if the right man is operating it, he got an idea and ordered a special team be established use this weapon to seek out these enemies and destroy them.
The small group created to carry out this directive is told that the money was unlimited, the resources was unlimited, and the support was unlimited. And the scope was also unlimited. It didn't matter whether the targets were in the U.S. or overseas, American citizens or foreigners. If they posed a threat, they were to be eliminated. The strike team of this small group consisted of two people, with just a handful of poeple knowing anything about the mission or the team members.
The younger of the two is Steven Dye, a technology wizard and the inventor of the rifle in question, the "SIKIM 1000 multiple-delivery killing tool". Though he hasn't any field experience, his knowledge of the capabilities is total and his enthusiasm almost as much.
The experienced leader is Con Duggan, a retired Marine Master Sergeant with years of sniper experience. Having worked for nearly a decade alongside a CIA agent in the jungles of Vietnam, his was the first name thought of by that agent, now Director of Operations for the CIA, when the group was founded.
Duggan, being retired and happily spending his time fishing and enjoying solitude, was reluctant to return to duty but eventually the proding of his friend worked and he agreed. Training a young, inexperienced operative like Dye wasn't something he looked forward to but the two soon hit it off and a partnership was created.
