History

During the Vietnam War, one of the most dangerous jobs was undertaken by a select few known as "tunnel rats."  
These unsung heroes were American, Australian, and New Zealand soldiers specially trained as combat engineers, who crawled through Viet Cong underground tunnels to perform perilous covert search.

I'm a medical statistician with a love for data analytics.

Tunnel rats gently prodded for armed mines in order to disarm them — and prayed that they survived with both their legs intact. Most men were volunteers and tended to be of smaller stature, making it easier for them to maneuver through the cramped subterranean spaces.⁠
