This was written by Timothy John's brother, Brian Johns a few days after Timothy's Death:

Senior Chief Timothy Johns (Explosive Ordinance Disposal (EOD) Technician) joined the Navy on July 18, 1989… The first in his family to serve since his grandfathers served in World War II. 

He served aboard the USS Theodore Roosevelt and USS George Washington. During that time, Johns supported Operation Restore Hope in Haiti and EOD operations in Bosnia. 
He supported operations in Afghanistan, destroying more than 100,000 pounds of leftover Soviet-era ordnance and he supported various missions and completed deployments to Djibouti, Africa and Iraq.

At the end of 2004, Johns reported back to EODMU2 in Virginia Beach, and deployed twice more to Iraq. It was on his second deployment during the summer of 2007, while supporting combat operations and clearing three roadside Improvised Explosive Devices (IEDs), that Johns was called away from that site to investigate a possible IED in a nearby home. More than 20 ground forces had been in and out for the building for about an hour, unharmed, and as luck would have it, after confirming the presence of an IED, Johns would be the one to set off the IED, stepping on a quarter-sized switch that was hidden under a stairwell.

The explosion launched a significant amount of shrapnel, hitting Johns, resulting in severe damage to his right arm. After spending a few months at Bethesda Naval Hospital and finally getting surgery at the Mayo Clinic in Rochester, Minnesota to reconstruct the radial head and lower wrist on his right arm, Johns was fortunate to return back to full duty with a new metal wrist.

In 2009, he was deployed to Kandahar Air Field, Afghanistan as the Leading Chief of Combined Explosive Exploitation Cell (CEXC) in support of Operation Enduring Freedom. 

During his years of service, Johns has earned numerous awards, including a Bronze Star with a V (for Valor), a Defense Meritorious Service Medal, a Purple Heart and two Combat Action Ribbons.

Farewell my hero, friend, brother and all AMERICAN badass! You will be missed as long as I draw breath. And at that time, we will meet again. 

Love you
