 When there is an emergency on land, nearly everyone knows to pick up the phone and call 911 for help. But when a ship's at sea, sailors only have each other to depend on in a crisis. Petty Officer Tony DeFilippo went aboard the landing platform dock USS Denver in Sasebo, Japan, to see how the crew is training to respond to a medical emergency or casualty situation. Wounded sailors lay scattered across the deck of USS Denver. The ship is out at sea, and a helicopter has crashed and exploded on the flight deck. Our job as MTT is to create real world, real life scenarios to train the Denver crew to respond to medical emergencies. This time it's just a drill, but that doesn't mean the crew is taking it lightly. I think we're really well. There was a couple of hiccups that we can remediate and correct in the future, but that's why we do the drills, and all in all we were very satisfactory. We did well, we were to save lives today. That responsibility doesn't just fall on the ship's medical personnel. It's everyone's job to save lives. Well, there's a lot less common on this ship than there are crew personnel, so we can't be everywhere at once, so it's important to maintain a level knowledge of medical treatment to casualties, that way when we can't be, there can be first aid given. We may have blocked access to certain parts of the ship, so we may actually be the casualties ourselves, so it's really important for everyone to be cross-trained. Ship is out at sea, and things go wrong. The sailors on board only have each other. Training like this makes sure the crew is ready for anything.
