 Everybody in the military, we fight the nation's battles. That's what we do. And I know if I got killed in battle somewhere, I would want my remains brought home to my mom, dad, family, wife. And I know they want the same. On a barge somewhere in the South China Sea, a team of deep sea diving soldiers are searching for something. So Army divers, we're more of a jack of all trades as far as metal tasks. We do underwater welding, cutting, hydraulic tools, surveys, port clearance, ships, husbandry. But here in Vietnam, Army divers are conducting a more unique mission. So we go to different sites around the world and look for POW and MIA personnel from all the conflicts that the US have been in. Check red. Check green. Check standby. We are looking for a helicopter that has no losses. So our job as the dive team is to moor a barge over the crash site. And then we do an archeological excavation dig of the crash site looking for any material evidence or osseous material that can correlate to the known losses. The Defense POW-MIA Accounting Agency, an organization dedicated to bringing back America's missing in action, enlists the help of the 7th Engineer Dive Detachment, who's conducting most of the diving. Through extensive historical research and investigation, the DPAA identify sites around the world where they think they'll find the remains of US service members. These missions are conducted on land, as well as at sea. We do exactly what the land team does. We dig a hole in the earth, we put it in a bucket, we screen it, the same exact process that they do, except ours is at 80 feet and we can't see it. The best thing in analogy is vacuuming your neighbor's house for the first time in the dark. Specifically to this site, it's about three or four feet of silt. So I don't know if anybody has gone through a swamp, but I went to one with my wife and she got out of a kayak and put her foot down and it went all the way to her hips. That's about like what it is, except you can't see in front of your face. And they don't have a lot of time to do it, either. Last DPA mission, we had six hours of bottom time. So we had six hours to do whatever we could for each diver, one diver. Now we have to split that six hours up into 55 minutes for each diver. We do like four or five dives a day for 55 minutes each. We're not even touching six hours. As divers, we gotta be worried about a lot of stuff down there, but you get to work. We have no time. You get down, get to your basket, get to your dredge, go to work. Probably the most dangerous challenge, however, are the risks of diving at this depth for this period of time. The deeper you go, the more decompression you're gonna owe. That's why you see us, you know, rushing up and they're rushing the guys up, sitting them down and having them put them in a chamber. To make the most of their limited time, they use a decompression chamber to ensure the divers don't suffer from decompression sickness. Your body builds up nitrogen in its system. And you breathe it out naturally. But when you're underwater and it's pressurized, it doesn't come out fast enough through natural respiration. So you have to make what are called decompression stops at certain depths so you can safely breathe off the amount of nitrogen to make it safe to come out. Despite the complexity of the work, the team never loses sight of why they're there. If you were lost for 75 years and your family didn't have closure, that'd be a big deal for a lot of people. It takes you to a more emotional point in your life where you think about how you can help those people. And for us specifically, it's in the water. So if we can get down to a dive side, get on bottom and search for these guys until we find them, that's what we're gonna do. And we're all extremely glad that we can get the opportunity to do that.
