I work in the parent organization for the lab in Edgewood Maryland. The lab in Utah belongs to a different command. I'm going to say what you probably expect me to say, which is that we've got really good people. We have people whose work was used in Africa against Ebola, who are working on bar-coding spores, synthetic biology, scanning suspicious mail for the White House and the UN, etc. If you remember the mission during which the U.S. neutralized the Syrian chemical weapons stockpiles, all the actual scientists and engineers but one or two came from our labs, and they also designed the equipment and went to sea to do the de-mil. You may remember it as the Cape Ray mission, but it should probably have been called the Edgewood mission.
One non-obvious reason people work for the Army is that we do things nobody else needs to do. So, for example, Edgewood lab is the only place in the country certified to remove level 4 hazards from explosives. You can't get that kind of excitement just anywhere.
To stay youthful, stay useful.
