Lightfoot has taken his specialization in explosives to levels unheard of, such as memorizing every manual on explosives, calculations in applying the most effective structural damage, and disarming just about every bomb and anti-personnel booby traps. His skill set is so overwhelming that he is the first person approached for consultation in identifying explosives that no one else is able to identify. His knowledge extends beyond explosives used by the US military and ventures into those used by foreign forces and other non-military applications. The only detriment is that he takes so much time in doing his job that it takes him twice as long to clear an area of tripwires and traps.
It may take a while for him to isolate and identify the very detonator which would give a clue to the perpetrators of a terrorist attack. However, his teammates rest easy that when they have him, they don't have to expect any nasty surprises.
