The team is about fifteen people that are willing to crawl in the illicit tunnels,
the hand-dug portion of the tunnels
and each person has a role they are subject matter experts that crawl investigate
and examine the way the tunnels are constructed
and if they do or do not cross the international border.
There is also a confined space rescue technicians they're above ground
and handle belay lines and "five to ones"
and tripod harnesses and whatever else safety needs we need including air quality meters,
forced air ventilation and all the safety requirements and permitting...
There's also the investigation side where we have agents assigned to the HSI task force
and those agents handle the investigations of the tunnel once they are discovered
and tie into possibly further into narcotics beyond the tunnel.
