A Master EOD technician, Silva has deployed seven times and served in Iraq and Afghanistan. Silva has served on protection missions for presidents and the Pope.

He has also been to all 50 states and five of the seven continents.

Silva earned a bachelor’s degree in liberal arts from Excelsior College. He previously served as the command sergeant major for the 79th EOD Battalion and 71st EOD Group. Both units are part of the 20th CBRNE Command.

A native of Long Beach, California, Silva is the senior enlisted Explosive Ordnance Disposal technician in the U.S. military.

Silva thanked the Soldiers and Army civilians from the 20th CBRNE Command for their service to the nation. He said the 20th CBRNE Command supports military operations around the world and domestic authorities across the nation.

Headquartered on Aberdeen Proving Ground, Maryland, in Northeast Maryland’s science, technology and security corridor, the 20th CBRNE Command is home to the majority of the Active-Duty U.S. Army’s EOD and Chemical, Biological, Radiological, Nuclear (CBRN) units, as well as the 1st Global Field Medical Laboratory, CBRNE Analytical and Remediation Activity, Weapons of Mass Destruction Coordination Teams and Nuclear Disablement Teams.

“Whether it’s a chemical attack or a radiological, biological or explosive hazard, our Soldiers and civilians are trained and ready to respond with precision, expertise and courage. It’s our ability to counter these dangers that ensures the safety of our forces, our homeland and our partners worldwide,” said Silva. “If our Soldiers are on the battlefield, something really bad just happened and everyone is looking to us to make it better.”

Silva said the Soldiers and Army civilians from the 20th CBRNE Command have to stay ready for their lifesaving and mission-enabling missions, whenever and wherever they are called to serve.

“I always ask our Soldiers, when does an incident start,” said Silva. “It started yesterday. It started at the combat training center, home station and Advanced Individual Training. It started when you raised your right hand and decided to become part of the 1 percent of Americans who do really hard things for the other 99 percent. Our enemies have been plotting and preparing their entire lives in many cases, when called, let’s give them the response they deserve. That means we train today so we are ready to go tomorrow.”

Silva said that the Soldiers and U.S. Army civilians from the 20th CBRNE Command routinely demonstrate their grit, bravery and proficiency when they “run toward the thing that everyone else is running away from.”

“Our Soldiers are not only technically proficient and capable of operating in austere conditions and under extreme pressure,” said Silva. “Every exercise, every mission, every moment you spend honing your craft, increases survivability, assures success and sends a clear message: the 20th CBRNE Command stands ready to protect, defend and prevail.”
