tl;dr they did something; so can you
“Forced marches” or “humps” are a regular part of military training, brisk walking over tough terrain while carrying gear that could help a soldier survive if stranded alone. These soldiers, participating in “Tough Ruck 2013,” were doing the 26 miles of the Boston Marathon to honor comrades killed in Iraq and Afghanistan, or lost to suicide and PTSD-related accidents after coming home.
When the explosion went off, Fiola and his group immediately went into tactical mode. “I did a count and told the younger soldiers to stay put,” Fiola says. “Myself and two other soldiers, my top two guys in my normal unit, crossed the street about 100 yards to the metal scaffoldings holding up the row of flags. We just absolutely annihilated the fence and pulled it back so we could see the victims underneath. The doctors and nurses from the medical tent were on the scene in under a minute. We were pulling burning debris off of people so that the medical personnel could get to them and begin triage.”
Once the victims were transported away for further medical care, Fiola and the others stood guard around the blast area. “We switched to keeping the scene safe, quarantining the area and preventing people from entering. There was a guy behind me covered, just covered, in his own blood, and I started to smell some smoke. I turn around to look and he’s actually on fire, from a piece of whatever caused the explosion. I saw the smoke coming from his pocket so I reached in and pulled it out. It was his handkerchief, on fire.”
