The 15 bomb technicians who died in the line of duty last year were honored at the Hazardous Devices School.
The school is on Redstone Arsenal, and it is the training site for every bomb technician in the country.
The memorial service included a roll call of 15 names, bell tolls, and roses to remember the 15 bomb technicians who died protecting communities across the country.
"It's the first thing the instructors see in the morning when they come in, and it's the last thing we see at night when we leave," bomb technician instructor Darrel Kandil said.
Kandil devoted 27 years of his life to being a bomb technician, and now he's an instructor at the Hazardous Devices School.
"It's important that we see that wall, and we give our best to train the bomb technicians as they come through here," Kandil said.
Kandil was also responsible for ringing the bell at the memorial service.
He told WAAY 31 the bell creates an echo that symbolizes the work bomb techs do across the country.
"It's got a lot of energy. You can equate that to bomb technicians. A lot of energy. Most bomb technicians are Type A personalities. They do this for the love of the job," Kandil said.
Kandil and the Hazardous Devices School director John Stewart told WAAY 31 they understand being a bomb tech does not come without its share of sacrifice.
"We'll never forget them. The sacrifices they paid, the sacrifices their families paid, means the world to us and it allows us the opportunity to live the way we live in the United States of America," Stewart said.
The Hazardous Devices School was established in 1971.
It was run jointly by the FBI and Army until the FBI accepted primary responsibility last September.
The school has trained more than 20,000 local, state, and federal first responders and bomb technicians nationwide.
