Grant McIntosh was the type of agent who volunteered for any mission coming down the pipe.  His philosophy would push him to the brink in 1983 when a terrorist suicide bomber crashed his vehicle into the Marine Barracks in Beirut Lebanon.  Grant McIntosh responded and took control of the scene and was the sole investigator until help would arrive days later.  Grant's determination and grit protecting the crime scene over the next few days, under fire from enemy forces, would place him into the history book of legendary NIS agents who responded when called to duty.
